Overview

Improved modulo routine for the 32S(ii). Also works on the 11C, 15C and 42S by using the rounding (RND) function. It does not use any storage registers and operates like a built-in function ie preserving Z and T. LASTX contains the unrounded value after completion. The only assumption is that the display format has to be compatible with the divisor.
