These are functions that are used to convert signed shorts & bytes to integers (since converting them to a BMax short or byte is useless as they're unsigned) and vice versa (e.g, integer->signed short). These are especially useful when you want to save space in binary formats. Thanks to Floyd for help with this (about a year ago, no idea if anyone remembers but I figured I'd throw that in). | |||||
