Similar to project management, where at least one of the three dimensions budged, objective and dead-line is not exactly defined, also for routines like the a. m. applies the uncertainty principle regarding size, runtime and accuracy. In other words: approvement of one of them is only regarded as real improvement if none of the others worsen thereby.
Here the 11C version of it:
- Code: Select all

11- 44 25 STO I | 22- 45 1 RCL 1 | 33- 45 0 RCL 0
Edit: HP41 version is one byte longer than before, now either error free computation ends at END.
