# ~=

math operators

Since v1.0.0

Available on all platforms

The `~=`

operator consumes three parameters from the top of the stack, two operands p1 and p2 and a tolerance factor lambda,
and pushes onto the stack true if *|p1-p2| < lambda*, i.e. the difference between the two operands is lesser than lambda.

The two parameters must be of numeric types.

The operator `~=`

is useful when making comparaisons between doubles, where floating point operations generate rounding errors.
