is_eqv

is_eqv(obj1, obj2)
      

Return true if obj1 and obj2 are equivalent, otherwise return false.

Is_eqv is similar to is_eq except that it return true for two numbers that are considered equal by the predicate number_is_eq. There is one exception for this rule though – is_eqv will return false for is_eqv(+0.0, -0.0), whereas number_is_eq will return true. This provides a way to distinguish between positive and negative zeros.

Examples:

is_eqv(38492948403840248034824037496494864917349749247947249749327482479,

// true
