Common implementation for SVCB-compatible resource records.
This is similar to PrettyPrint::format but the result has no breaks.
maxwidth, newline and genspace are ignored.
The invocation of breakable in the block doesn’t break a line and is treated as just an invocation of text.
Returns one of the following:
The maximum-valued element from self.
A new array of maximum-valued elements from self.
Does not modify self.
With no block given, each element in self must respond to method <=> with a numeric.
With no argument and no block, returns the element in self having the maximum value per method <=>:
[1, 0, 3, 2].max # => 3
With non-negative numeric argument count and no block, returns a new array with at most count elements, in descending order, per method <=>:
[1, 0, 3, 2].max(3) # => [3, 2, 1] [1, 0, 3, 2].max(3.0) # => [3, 2, 1] [1, 0, 3, 2].max(9) # => [3, 2, 1, 0] [1, 0, 3, 2].max(0) # => []
With a block given, the block must return a numeric.
With a block and no argument, calls the block self.size - 1 times to compare elements; returns the element having the maximum value per the block:
['0', '', '000', '00'].max {|a, b| a.size <=> b.size } # => "000"
With non-negative numeric argument count and a block, returns a new array with at most count elements, in descending order, per the block:
['0', '', '000', '00'].max(2) {|a, b| a.size <=> b.size } # => ["000", "00"]

Returns one of the following:
The minimum-valued element from self.
A new array of minimum-valued elements from self.
Does not modify self.
With no block given, each element in self must respond to method <=> with a numeric.
With no argument and no block, returns the element in self having the minimum value per method <=>:
[1, 0, 3, 2].min # => 0
With non-negative numeric argument count and no block, returns a new array with at most count elements, in ascending order, per method <=>:
[1, 0, 3, 2].min(3) # => [0, 1, 2] [1, 0, 3, 2].min(3.0) # => [0, 1, 2] [1, 0, 3, 2].min(9) # => [0, 1, 2, 3] [1, 0, 3, 2].min(0) # => []
With a block given, the block must return a numeric.
With a block and no argument, calls the block self.size - 1 times to compare elements; returns the element having the minimum value per the block:
['0', '', '000', '00'].min {|a, b| a.size <=> b.size } # => ""
With non-negative numeric argument count and a block, returns a new array with at most count elements, in ascending order, per the block:
['0', '', '000', '00'].min(2) {|a, b| a.size <=> b.size } # => ["", "0"]

Returns the remainder after dividing self by other.
Examples:
11.remainder(4) # => 3 11.remainder(-4) # => 3 -11.remainder(4) # => -3 -11.remainder(-4) # => -3 12.remainder(4) # => 0 12.remainder(-4) # => 0 -12.remainder(4) # => 0 -12.remainder(-4) # => 0 13.remainder(4.0) # => 1.0 13.remainder(Rational(4, 1)) # => (1/1)
Returns 1.
Returns the imaginary value for self:
Complex.rect(7).imag # => 0 Complex.rect(9, -4).imag # => -4
If self was created with polar coordinates, the returned value is computed, and may be inexact:
Complex.polar(1, Math::PI/4).imag # => 0.7071067811865476 # Square root of 2.
Returns the denominator of self, which is the least common multiple of self.real.denominator and self.imag.denominator:
Complex.rect(Rational(1, 2), Rational(2, 3)).denominator # => 6
Note that n.denominator of a non-rational numeric is 1.
Related: Complex#numerator.
Returns 1 if either self.real.infinite? or self.imag.infinite? is true, nil otherwise:
Complex.rect(Float::INFINITY, 0).infinite? # => 1 Complex.rect(1, 1).infinite? # => nil
Related: Numeric#infinite?, Float#infinite?.
Returns the remainder after dividing self by other.
Of the Core and Standard Library classes, only Float and Rational use this implementation.
Examples:
11.0.remainder(4) # => 3.0 11.0.remainder(-4) # => 3.0 -11.0.remainder(4) # => -3.0 -11.0.remainder(-4) # => -3.0 12.0.remainder(4) # => 0.0 12.0.remainder(-4) # => 0.0 -12.0.remainder(4) # => -0.0 -12.0.remainder(-4) # => -0.0 13.0.remainder(4.0) # => 1.0 13.0.remainder(Rational(4, 1)) # => 1.0 Rational(13, 1).remainder(4) # => (1/1) Rational(13, 1).remainder(-4) # => (1/1) Rational(-13, 1).remainder(4) # => (-1/1) Rational(-13, 1).remainder(-4) # => (-1/1)
Returns nil, -1, or 1 depending on whether self is finite, -Infinity, or +Infinity.
Returns zero.
Returns the denominator (always positive).
Returns:
1, if self is Infinity.
-1 if self is -Infinity.
nil, otherwise.
Examples:
f = 1.0/0.0 # => Infinity f.infinite? # => 1 f = -1.0/0.0 # => -Infinity f.infinite? # => -1 f = 1.0 # => 1.0 f.infinite? # => nil f = 0.0/0.0 # => NaN f.infinite? # => nil
Returns the denominator (always positive). The result is machine dependent.
See also Float#numerator.
Returns true if path matches against pattern. The pattern is not a regular expression; instead it follows rules similar to shell filename globbing. It may contain the following metacharacters:
*Matches any file. Can be restricted by other values in the glob. Equivalent to /.*/x in regexp.
*Matches all regular files
c*Matches all files beginning with c
*cMatches all files ending with c
*c*Matches all files that have c in them (including at the beginning or end).
To match hidden files (that start with a .) set the File::FNM_DOTMATCH flag.
**Matches directories recursively or files expansively.
?Matches any one character. Equivalent to /.{1}/ in regexp.
[set]Matches any one character in set. Behaves exactly like character sets in Regexp, including set negation ([^a-z]).
\Escapes the next metacharacter.
{a,b}Matches pattern a and pattern b if File::FNM_EXTGLOB flag is enabled. Behaves like a Regexp union ((?:a|b)).
flags is a bitwise OR of the FNM_XXX constants. The same glob pattern and flags are used by Dir::glob.
Examples:
File.fnmatch('cat', 'cat') #=> true # match entire string File.fnmatch('cat', 'category') #=> false # only match partial string File.fnmatch('c{at,ub}s', 'cats') #=> false # { } isn't supported by default File.fnmatch('c{at,ub}s', 'cats', File::FNM_EXTGLOB) #=> true # { } is supported on FNM_EXTGLOB File.fnmatch('c?t', 'cat') #=> true # '?' match only 1 character File.fnmatch('c??t', 'cat') #=> false # ditto File.fnmatch('c*', 'cats') #=> true # '*' match 0 or more characters File.fnmatch('c*t', 'c/a/b/t') #=> true # ditto File.fnmatch('ca[a-z]', 'cat') #=> true # inclusive bracket expression File.fnmatch('ca[^t]', 'cat') #=> false # exclusive bracket expression ('^' or '!')

File.fnmatch('.*', '.profile') #=> true File.fnmatch('**/*.rb', 'main.rb') #=> false File.fnmatch('**/*.rb', './main.rb') #=> false File.fnmatch('**/*.rb', 'lib/song.rb') #=> true File.fnmatch('**.rb', 'main.rb') #=> true File.fnmatch('**.rb', './main.rb') #=> false File.fnmatch('**.rb', 'lib/song.rb') #=> true File.fnmatch('*', 'dave/.profile') #=> true File.fnmatch('**/foo', 'a/b/c/foo', File::FNM_PATHNAME) #=> true File.fnmatch('**/foo', '/a/b/c/foo', File::FNM_PATHNAME) #=> true File.fnmatch('**/foo', 'c:/a/b/c/foo', File::FNM_PATHNAME) #=> true File.fnmatch('**/foo', 'a/.b/c/foo', File::FNM_PATHNAME) #=> false File.fnmatch('**/foo', 'a/.b/c/foo', File::FNM_PATHNAME | File::FNM_DOTMATCH) #=> true
Returns false
Returns the integer minute of the hour for self, in range (0..59):
t = Time.new(2000, 1, 2, 3, 4, 5, 6) # => 2000-01-02 03:04:05 +000006 t.min # => 4
