RE: Saturn family calculator performance
My reference puts the entry point for the UserRPL function ATAN at 1B79C.

SysRPL %ATAN is 2AD21 but when calling this function you have to be absolutely sure that you have a single-precision real number in level 1 of the stack. SysRPL functions perform no sanity checks. They assume that the number and type of values passed to them on the stack are correct and you get totally unpredictable results if this is not the case.
