I had a quick look at how ZVision uses sscanf, and something like that sounds
good, yes.

If you want something that actually compiles, try:

        float y;
        sscanf("30.981", "%f", &y);
        printf("Test dot: %f\n", y);
        sscanf("30,981", "%f", &y);
        printf("Test comma: %f\n", y);


You should get as output:

Test dot: 30.981001
Test comma: 30.000000
