Returns self.

Returns an array; [num, 0].

Returns an array; [num, 0].

Returns an array containing the quotient and modulus obtained by dividing num by numeric.

If q, r = x.divmod(y), then

q = floor(x/y)
x = q*y + r

The quotient is rounded toward negative infinity, as shown in the following table:

 a    |  b  |  a.divmod(b)  |   a/b   | a.modulo(b) | a.remainder(b)

Examples

11.divmod(3)        #=> [3, 2]
11.divmod(-3)       #=> [-4, -1]
11.divmod(3.5)      #=> [3, 0.5]
(-11).divmod(3.5)   #=> [-4, 3.0]

x.modulo(y) means x-y*(x/y).floor.

Equivalent to num.divmod(numeric)[1].

See Numeric#divmod.

Returns true if num is a real number (i.e. not Complex).

Returns true if num is greater than 0.

Returns true if num is less than 0.

Returns true if the length of self is zero, false otherwise:

"hello".empty? # => false
" ".empty? # => false
"".empty? # => true

Replaces the contents of str with the corresponding values in other_str.

s = "hello"         #=> "hello"
s.replace "world"   #=> "world"

Prepends each string in other_strings to self and returns self:

s = 'foo'
s.prepend('bar', 'baz') # => "barbazfoo"
s                       # => "barbazfoo"
