Qick Conversion Question -- Please Help

[DougCa]

Hi:

I have this function, converting the ASCII value in to a corresponding HEX and then doing a bitshift by 4. It does octal.


iReturnValue = (iReturnValue <<= 4) | ( (cmd % '0') - 7 * (cmd / 'A') );

if I want to change this to convert from to an integer from hexascii what needs to be changed?

iReturnValue = (iReturnValue >>= 4) | ( (cmd % '0') - 7 * (cmd / 'A') );

I thought this above, but it does not seem to work.

Thanks,
Doug
