Method: Integer#modulo

Defined in:

numeric.c

#%(other) ⇒ Object

Returns self modulo other as a real number.

For integer n and real number r, these expressions are equivalent:

n % r
n-r*(n/r).floor
n.divmod(r)[1]

See Numeric#divmod.

Examples:

10 % 2              # => 0
10 % 3              # => 1
10 % 4              # => 2

10 % -2             # => 0
10 % -3             # => -2
10 % -4             # => -2

10 % 3.0            # => 1.0
10 % Rational(3, 1) # => (1/1)
