compareTypeSafe
Description copied from class:Value
Compare this value against another value given that the values are of the same data type.- Specified by:
compareTypeSafe
in classValue
- Parameters:
v
- the other valuemode
- the compare modeprovider
- the cast information provider- Returns:
- 0 if both values are equal, -1 if the other value is smaller, and 1 otherwise
-
divide
Description copied from class:Value
Divide by a value and return the result. -
equals
Description copied from class:Value
