Returns zero.
Returns nil, -1, or 1 depending on whether the value is finite, -Infinity, or +Infinity.
Returns the denominator (always positive).
Returns nil, -1, or 1 depending on whether the value is finite, -Infinity, or +Infinity.
(0.0).infinite? #=> nil (-1.0/0.0).infinite? #=> -1 (+1.0/0.0).infinite? #=> 1
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 files 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 true if ios is binmode.
Returns the minimum value in the range. Returns nil if the begin value of the range is larger than the end value. Returns nil if the begin value of an exclusive range is equal to the end value.
