Integer part and other little tricks (CASIO fx-50F)

[damaltor]

I have most of the casios of that generation. i never understood why someone would want not a do-if-true or even skip-if-true, but a restart-if-true condition... combined with a very low number of storable steps and only two possible conditions (x>0 and x<=M), that 50f was a very quirky device.
