Dear all,

The command strconv.ParseInt("256", 8, 8) should not return an error, because octal 256 is decimal 174 which fits into 8 bits.  Right?

I'm asking, because actually running this command gives 'strconv.ParseInt: parsing "256": value out of range'!  https://play.golang.org/p/gNKN0kKLfDd

What am I overlooking here?

All the best,
Jochen

An int8 has a range of -128 to +127. You may be looking for strconv.ParseUint if you want an 8 bit unsigned int?

Not unless the int is unsigned.
