Example: float
The following example converts the initial portion of the string, s, to a float.
double atof( const char * string); // Explicit declaration float x; char * s = "7.2339 by these hilts or I am a villain else"; x = atof(s);
// The %.2f formatting string limits the output to 2 decimal places
lr_output_message ("%.2f", x);
Example: Output:
vuser_init.c(11): 7.23
