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
*c
Matches 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.

Returns the remainder from dividing by the value.
x.remainder(y) means x-y*(x/y).truncate
Returns nil, -1, or +1 depending on whether the value is finite, -Infinity, or +Infinity.

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
Sets the stream’s data mode as binary (see Data Mode).
A stream’s data mode may not be changed from binary to text.
Returns true if the stream is on binary mode, false otherwise. See Data Mode.
Returns the minimum value in self, using method <=> or a given block for comparison.
With no argument and no block given, returns the minimum-valued element of self.
(1..4).min # => 1 ('a'..'d').min # => "a" (-4..-1).min # => -4
With non-negative integer argument n given, and no block given, returns the n minimum-valued elements of self in an array:
(1..4).min(2) # => [1, 2] ('a'..'d').min(2) # => ["a", "b"] (-4..-1).min(2) # => [-4, -3] (1..4).min(50) # => [1, 2, 3, 4]
If a block is given, it is called:
First, with the first two element of self.
Then, sequentially, with the so-far minimum value and the next element of self.
To illustrate:
(1..4).min {|a, b| p [a, b]; a <=> b } # => 1
Output:
[2, 1] [3, 1] [4, 1]
With no argument and a block given, returns the return value of the last call to the block:
(1..4).min {|a, b| -(a <=> b) } # => 4
With non-negative integer argument n given, and a block given, returns the return values of the last n calls to the block in an array:
(1..4).min(2) {|a, b| -(a <=> b) } # => [4, 3] (1..4).min(50) {|a, b| -(a <=> b) } # => [4, 3, 2, 1]
Returns an empty array if n is zero:
(1..4).min(0) # => [] (1..4).min(0) {|a, b| -(a <=> b) } # => []
Returns nil or an empty array if:
The begin value of the range is larger than the end value:
(4..1).min # => nil (4..1).min(2) # => [] (4..1).min {|a, b| -(a <=> b) } # => nil (4..1).min(2) {|a, b| -(a <=> b) } # => []
The begin value of an exclusive range is equal to the end value:
(1...1).min # => nil (1...1).min(2) # => [] (1...1).min {|a, b| -(a <=> b) } # => nil (1...1).min(2) {|a, b| -(a <=> b) } # => []
Raises an exception if either:
self is a beginless range: (..4).
A block is given and self is an endless range.
Related: Range#max, Range#minmax.
Returns the maximum value in self, using method <=> or a given block for comparison.
With no argument and no block given, returns the maximum-valued element of self.
(1..4).max # => 4 ('a'..'d').max # => "d" (-4..-1).max # => -1
With non-negative integer argument n given, and no block given, returns the n maximum-valued elements of self in an array:
(1..4).max(2) # => [4, 3] ('a'..'d').max(2) # => ["d", "c"] (-4..-1).max(2) # => [-1, -2] (1..4).max(50) # => [4, 3, 2, 1]
If a block is given, it is called:
First, with the first two element of self.
Then, sequentially, with the so-far maximum value and the next element of self.
To illustrate:
(1..4).max {|a, b| p [a, b]; a <=> b } # => 4
Output:
[2, 1] [3, 2] [4, 3]
With no argument and a block given, returns the return value of the last call to the block:
(1..4).max {|a, b| -(a <=> b) } # => 1
With non-negative integer argument n given, and a block given, returns the return values of the last n calls to the block in an array:
(1..4).max(2) {|a, b| -(a <=> b) } # => [1, 2] (1..4).max(50) {|a, b| -(a <=> b) } # => [1, 2, 3, 4]
Returns an empty array if n is zero:
(1..4).max(0) # => [] (1..4).max(0) {|a, b| -(a <=> b) } # => []
Returns nil or an empty array if:
The begin value of the range is larger than the end value:
(4..1).max # => nil (4..1).max(2) # => [] (4..1).max {|a, b| -(a <=> b) } # => nil (4..1).max(2) {|a, b| -(a <=> b) } # => []

Raises an exception if either:
self is a endless range: (1..).
A block is given and self is a beginless range.

Sets the data mode in self to binary mode; see Data Mode.
Sets the scan pointer to the end of the string and clear matching data.
Puts ARGF into binary mode. Once a stream is in binary mode, it cannot be reset to non-binary mode. This option has the following effects:
Newline conversion is disabled.
Encoding conversion is disabled.
Content is treated as ASCII-8BIT.
Returns true if ARGF is being read in binary mode; false otherwise. To enable binary mode use ARGF.binmode.
For example:
ARGF.binmode? #=> false ARGF.binmode ARGF.binmode? #=> true
Terminate option processing; returns nil if processing has already terminated; otherwise returns self.
