verify the sign of difference of two objects

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

verify(expr1, expr2, greater_than)

verify(expr1, expr2, greater_equal)

verify(expr1, expr2, equal)

verify(expr1, expr2, less_equal)

verify(expr1, expr2, less_than)

Parameters

expr1, expr2

-

anything, assumed to be of type algebraic

Description

• 

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.
