[OT] Hexadecimal Bitmask

[Amy L.]

I understand how to calculate and use binary bitmasks. However, I am having
a hard time figuring out how to work with Hexadecimal Bitmasks. I figured
it would be the same thing as doing a binary bitmask (i.e. 16^0, 16^1, 16^2,
...., 16^n). For example I figured the decimal number 124 would represent
7C00 in terms of a hex bitmask? Is that right or wrong?

Thanks
Amy,

Hex is a numbering system. The most significant digit is on the left, the
least is on the right. 124 = 7C, not 7C00.

If you are trying to be big-endian, realize that the compiler will handle
the representation in binary for you, so there is no reason to code the byte
order that way.
