Code:

STO 0 X<>Y X=0 GTO 015 RCL 0 - 32 x 5 ÷ 9 = GTO 000 RCL 0 x 9 ÷ 5 + 32 =

May I ask two questions?

- Why does the program require a data register? Why don't you simply recall the input with another X<>Y ?

- The °F to °C conversion calculates "<input> – 32 x 5 / 9". Any decent algebraic calculator I know of would do the multiplication/division before the subtraction. Does the 12C Platinum really ignore this? So would "1+2x3=" really return 9 instead of 7 ? If the resul is (correctly) 7 the program needs parantheses or an additional "=".

Edit: reading the 12C Platinum manual, I just realized that indeed this calculator does not calculate the multiplication and division first. It simply executes the operations from left to right. Unbelievable... #-(
