Hex to decimal replacement
|
|
| Tim Frink 2007-12-21, 7:33 am |
| Hi,
I've a C source code file which contains an array used as
input for a benchmark. The array look like that (contains
in reality over 60000 elements):
float a[] = {0x80, 0x43, 0x14 };
For some technical reasons, I'd like to covert these hex values
to their corresponding decimal numbers resulting in an array:
float a[] = {128, 67, 24 };
How could I do that with a script?
Regards,
Tim
