Hey guys, I'm trying to learn Binary and Hexadecimal math, and I would like to know how to convert a Hexadecimal number to WORD. Is this even possible, or do I have the facts messed up?

In the Frhed Hex Editor, I have a program opened. Examining the Hex code, I see a 00 in hex. Looking on the bottom on the status bar, I see that the WORD conversion is 512. How is this calculation achieved? Thanks for your inputs.

It sounds far-fetched that 00 hex "converts" to 512 in any number system.

If you want to see the ASCII equivalent of hex bytes, get a chart or a hex editor/viewer.

This string:

40 65 63 68 6F 20 6F 66 66

in ASCII is:

@echo off

=====================================
If at first you don't succeed, you're about average.

M2

You're right. 00 02 was what I was meaning to say...I was confused at the time I wrote it.

In Frhed, 00 02 is 512 in WORD. How is this calculation achieved? I thought 512 was 200 in Hexadecimal Notation. But 00 02 seems reversed than 200. I'm probably confusing you, but I'm confused myself.

Hex notation is shorthand to handle binary digits and you do not have to confuse math with tech issues; i.e. you are right to say dec 512 is hex 0200 and that is stored in a word (two bytes), but x86 based microprocessors handle a word in a revere way: lowest byte comes first and then the highest. So what you read as word 0200 actually is stored as 0002 in RAM.

That is a tech issue related to memory architecture and has nothing to do with math.

Ok, thanks very much!
