Convert string to number

Archiver

Does anyone know an easy way to convert from a number represented as
2 ascii characters into the actual number that represents in decimal.

Thanks.

Since the ASCII character for "0" is 48, you can subtract 48 from a
character to get its decimal value. If you have a two digit value, you
can do it like this:

myVal = 10 * (char10 - "0")
myVal = myVal + (char01 - "0")

... where char10 is the 10's digit character and char01 is the 1's digit
character.

Hi,

If you're receiving these ASCII characters serially, you should use the
SERIN conversion modifier DEC2. I hope this helps.
