Converting ascii hex to decimal

[Jomile]

I found some example code that converts ascii to decimal and it works well. If someone could explain why the code below doesnt I would appreciate it

I wanted to convert a 3 digit number to decimal so i wrongfully used this code below.

Assuming that your 3 digits could be from 000 to 999, the result is
greater than an 'int' can hold. In CCS, an 'int' is an unsigned 8-bit
variable and can only hold from 0-255. So you need to declare 'test'
as an int16 as shown in bold below.

Also, you need to force the compiler to do 16-bit math on the first
part of the expression below. You can do this by casting the '100'
to a 'long'. This is done by appending an 'L' on the end, as shown below:

Thanks PCM programmer, that did it. I was not aware of the 'L' to do 16-bit math. Much appreciation
