String to Decimal

str2dec is a function that receives a string representing a number as an input and has two integers as out-params.

• num - the integer representation of the string value
• expo - the exponent of the string value a numeric representation is num * 10^-expo

Test

Compile test: gcc str2dec.c test.c -o str2dec

Run: `./str2dec 1234 +12.34 0.01234 -1.234E3 -1.234E+3 -1.234E-3`

Results:
num 1234         expo 0
num 1234         expo 2
num 1234         expo 5
num -1234        expo 0
num -1234        expo 0
num -1234        expo 6
