Hi,

I have an application where I am reading values from a text file on the NXT and I need to convert some of the read numbers from their character representation to numbers (short/int). For example;

sReadVal = "12";

What is the best way to convert this to a short of 12? Are there any string-to-number conversion functions available?

Thanks,
Chris

I don't have RobotC in front of me but I vaguely recall it may support sscanf. If not, check if it supports atoi. If not, you can always write your own

Hi,

I don't think RobotC has any of the conversion functions built-in. Certainly not atoi or sscanf. I've written my own for now, but if there are any built-in functions to make it easier, I'd like to know.

Thanks,
Chris

There are. I've used atoi in my programs before. I believe sscanf works as well but I'm not sure how to use it.

^^This is correct. Setting a numeric variable (int, long, etc) using atoi and a string will convert the "12" to a numeric 12.
