%T function question
Hey everyone does anyone know if %T function exists in Plus42 or 50g?
Copying from one of the financial calculator books: Quote:And with the key, you can find what percent one number is of another number or of the sum of several numbers. You are finding proportions when you use [%T]. |

RE: %T function question
There is no built in %T function in Plus42 but it’s easy to program :
Code: 01 LBL "%T" (From HP KEY NOTES V5N3 Dec 81 p13) |

RE: %T function question
To complete what nickapos contributed, I have attached a PDF with three usage options for percentages. I had not sufficiently taken into account the great advantage of the %, %CH and %T functions in relation to the fact that once the function is executed it preserves the original value of the Y register. This provides great agility in repetitive calculations.
This text was intended primarily for the HP-67 and HP 35s calculators Pedro PS: Sorry I have attached the wrong file, now correct |

FYI the HP-67 implementation and the snippet of code for HP-41/42 preserve the original number, but the implementation for HP-50g/newRPL does not. Interesting implementation difference there. |
