RE: integer division
First calculate R:
R=MOD(C*1E12,X) then Q=(C*1E12-5E11*X-R)/X+5E11 The trick is to shift the result Q by -5E11 to avoid the rounding in the division. I leave the implementation on the HP42S as an exercice... This reminds me the famous S&S math challenges some years ago - Hello Valentin, if you are still around! J-F Added: Unfortunatly, this formula still fails for some cases... Needs more tuning, finally will not be so simple. |
