Hex to unsigned long?

[Jumpem]

I have a simulation project I am doing.

One of the functions takes an unsigned long. I am given 2^15 or 00007FFF for it to be. How do I get that hex value into long?

converting hex value into long makes absolutely no sense.

edit: can you rephrase the question? you are comparing apples to oranges with that question.

Nevermind, I'm a complete idiot. It's just 2^15 = 32,768.

The professor gave us the maximum memory size for our simulator as 00007FFF. But the library function that implements memory takes a long.

Do you really mean an ASCII string of hex characters?

In most languages no such conversion is needed unless it's ASCII.

unsigned long foo = 0x07fff ; // C++

i guess you meant hex to decimal? or hex to binary?

No this number is a constant that gets used at start up when creating the simulated "memory".

even so, i don't see what the problem is. The max memory is 32KB. Your function takes a long....not any different from taking a unsigned int.

Hex to decimal. It was simple, I just wasn't looking at it right.

He gave us the hex value to use on paper. But the code needed the decimal value.

ahh i remember the days of easy programming problems... 🙂

Not in most languages:

unsigned long foo = 0x07fff ; // C++

This project is going to be far from easy. We have to simulate a MIPS CPU.

i guess for a comp arch class? good luck to you sir!

Yeah, it's comp arch. It's really kicking my butt. I transfered here from another school, and got transfer credit for the prereq course. Needless to say I'm not quite prepared for what I've gotten myself into.
