math

Convenience macros for 16 bit arithmetic operations such as adding, subtraction, increment, decrement.

Usage

The math module consists of following files:

• lib/math-global.asm
• lib/math.asm

All files located directly in lib directory can be imported to your source code using #import directive, i.e.:

#import "common/lib/math.asm"

All library files located directly under lib directory has #importonce declared which means they can be safely imported multiple times - only first import is effective.

Library files with -global.asm suffix contains globalized elements that can be directly accessed from root namespace. All names of these elements (except labels) are prefixed with c64lib_ prefix.
