SYNOPSIS
|
|
meq(x, y, md)
|
|
|
|
TYPES
|
|
x real
|
|
y real
|
|
md real
|
|
|
|
return 0 or 1
|
|
|
|
DESCRIPTION
|
|
Returns 1 if and only if for some integer n, x - y = n * md, i.e.
|
|
x is congruent to y modulo md.
|
|
|
|
If md = 0, this is equivalent to x == y.
|
|
|
|
For any x, y, md, meq(x, y, md) = ismult(x - y, md).
