Parses command line arguments argv in order. When a block is given, each non-option argument is yielded.

Parses command line arguments argv in permutation mode and returns list of non-option arguments.

Same as permute, but removes switches destructively. Non-option arguments remain in argv.

Wrapper method for getopts.rb.

params = ARGV.getopts("ab:", "foo", "bar:", "zot:Z;zot option")
# params[:a] = true   # -a
# params[:b] = "1"    # -b1
# params[:foo] = "1"  # --foo
# params[:bar] = "x"  # --bar x
# params[:zot] = "z"  # --zot Z

See getopts.

Loads options from file names as filename. Does nothing when the file is not present. Returns whether successfully loaded.

filename defaults to basename of the program without suffix in a directory ~/.options.

Returns the regexp.

m = /a.*b/.match("abc")
m.regexp #=> /a.*b/

Returns an array with both a numeric and a big represented as Bignum objects.

This is achieved by converting numeric to a Bignum.

A TypeError is raised if the numeric is not a Fixnum or Bignum type.

(0x3FFFFFFFFFFFFFFF+1).coerce(42)   #=> [42, 4611686018427387904]

provides a unified clone operation, for REXML::XPathParser to use across multiple Object types

Returns the largest number less than or equal to int in decimal digits (default 0 digits).

Precision may be negative. Returns a floating point number when ndigits is positive, self for zero, and floor down for negative.

1.floor        #=> 1
1.floor(2)     #=> 1.0
15.floor(-1)   #=> 10

Returns int modulo other.

See Numeric#divmod for more information.

Returns the remainder after dividing big by numeric as:

x.remainder(y) means x-y*(x/y).truncate

Examples

5.remainder(3)    #=> 2
-5.remainder(3)   #=> -2
5.remainder(-3)   #=> 2
-5.remainder(-3)  #=> -2

-1234567890987654321.remainder(13731)      #=> -6966
-1234567890987654321.remainder(13731.24)   #=> -9906.22531493148
