RE: (41C) Quotient and Remainder
(04-18-2023 05:40 AM)Ángel Martin Wrote: the OS does that for you: the truncated 10-digit value is placed in C, while the 13-digit value is left in registers {A,B} No, the OS provides the rounded 10-digit value in C. If we need the truncated 10-digit value, we need to build it from {A,B} (very similar to the HP-71B math code that I know much better) So QREM may give the wrong quotient when the dividend is >1E10, e.g.: 2E10 3 QREM --> Q=6666666667 (checked on V41-R9I, Lib#4-R59b, SandMath-R7) J-F Edit: not really sure of the SandMath version I downloaded from TOS. The Web page and the manual both say Release 7, but the ROM says R6 (HL-6B, SM-6B) ? |
