Hi, D, a computer programmers calculator = a calculator found on Windows computer set to programming. R, I tried 'Set to DEC and BYTE or BIN' 1 OR 1 then switched to WORD. =1. FF or FF worked. Also x256. Would you clarify 'OR' a bit more please? C Last edited by camerart; January 29th, 2018 at 01:44 AM.

What base are the numbers you want to enter in? if they are hex, just type the MSB followed by the MSByte with the calculator in Hex mode. If your numbers are decimal, type the MSByte, x256 then add the LSByte, you can use any calculator for this unless you then want to convert the result to Hex after. If this is something you need to do more than once, use Excel or google sheets, they handle Hex conversions for you too.

With a calculator I have on the computer (shown in previous post) set to DEC, I can't type say 220, it stops at 22. If i know the HEX, it all work. C

Hi, I've been playing with the computer calculator, and got confused by ''s appearing. So I don't think the calculator is for me. In the program I'm programming, I added a little routine, that does this for me. I have to post the results online to get them verified each time, instead of the calculator. Thanks to all. C.
