modulo-x

modulo - floored division implementation.

module.exports(dividend, divisor)number

The notation “x modulo y” (y must be finite and nonzero) computes a value k
of the same sign as y (or zero) such that abs(k) < abs(y) and x-k = q × y
for some integer q.

Donald Knuth described floored division where the quotient is defined by
the floor function q = ⌊a/n⌋ and thus according to equation the remainder
would have the same sign as the divisor. Due to the floor function, the
quotient is always rounded downwards, even if it is already negative.

Kind: Exported function
Returns: number - The integer remainder.

Param Type Description
dividend number The integer to find the remainder of.
divisor number The integer to divide by.

Example

  1. import modulo from 'modulo-x';
  2. console.log(modulo(1, 0x1000000)); // 1
  3. console.log(modulo(-1, 0x1000000)); // 16777215 (2^24-1)
