Parameters
Description
Examples
verify(expr1, expr2, greater_than)
verify(expr1, expr2, greater_equal)
verify(expr1, expr2, equal)
verify(expr1, expr2, less_equal)
verify(expr1, expr2, less_than)
expr1, expr2
-
anything, assumed to be of type algebraic
The verify(expr1, expr2, equal) function returns true if and false if the call to signum returns a numeric object. Otherwise, it returns FAIL.
The verify(expr1, expr2, greater_than) returns true if , , and , and false if either of the first two calls to signum return a nonzero numeric value or if the third returns or . Otherwise, it returns FAIL.
The behavior is similar for the remaining verifications.
The verify/equal function is symmetric in its arguments while the others are not.
If either expr1 or expr2 is not of type algebraic, then false is returned.
