NAME
    ismult - whether a value is a multiple of another

SYNOPSIS
    ismult(x, y)

TYPES
    x		real
    y		real

    return	int

DESCRIPTION
    Determine if x exactly divides y.  If there exists an integer k
    such that:

	x == y * k

    then return 1, otherwise return 0.

EXAMPLE
    > print ismult(6, 2), ismult(2, 6), ismult(7.5, 2.5)
    1 0 1

    > print ismult(4^67, 2^59), ismult(13, 4/67), ismult(13, 7/56)
    1 0 1

LIMITS
    none

LIBRARY
