I don't think it can be squeezed into an HP-16C. I implemented it in Java, and the classes are about 5 KB in total. You can get my Java code, if you want, but it is just a translation of the NetRexx code.

This quick and dirty HP16C program must do for the compressor !

Hi, Patrice;
I see you are trying to format your listing. Please, let me know if this is what you want: 001- LBL C STO 0 8 8 8 AND STO 2 RCL 0 XOR
To accomplish this, add a [pre] in the begining of the listing, and a [/pre] in the end of it. Like this: [pre]001- LBL C STO 0 8 8 8 AND STO 2 RCL 0 XORand, of course, congrats. Your suggestion is a very good example of efficient programming with the HP16C. Cheers. Luiz (Brazil) ▼

Thanks for the tip, I'am not used to poste often on this forum.

I think this is the IEEE 754 binary floating point format. The question was about the upcoming IEEE 754R decimal format. It is a kind of Huffman compressed BCD, with some bits carrying information on both the exponent and the coefficient (mantissa). This gives 16 digits of precision, with an exponent from -383 to 384. This format is designed to be hardware-friendly, so a decimal FPU can easily split it into BCD digits. The IEEE 754R guys think that decimal arithmetic will take over from binary. As I said, it is 5 KB of Java classes, and though RPN may be more compact, there is no way to squeeze it into an HP 16C.
