[Bug c/25498] atof conversion error

Yes, but when I set the string to "60342935.00", I still get the same
result - 60342936 from atof() whereas if the covert to variable is
double (instead of float) I get the right result - 60342935.

I still think atof(##################) should return the right result,
whatever the precision.

Thanks.

This is called float not having enough precession.  This is not a bug.
Please
read what floating point is.

The full testcase looks like:
#include <stdio.h>
#include <string.h>

#include <stdlib.h>

int main(void)
{
        char currConv[9];
        float currConvf;
        memset(currConv, '\0', sizeof(currConv));
        memcpy(currConv, "60342935", 8);
        currConv[8] = 0;
        currConvf = atof(currConv);
        printf("%f\n", currConvf);
}
