Example: atof

The following example converts the initial portion of the string, s, to a float.

double atof( const char *string); 
vuser_init() {
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);
return 0;
Example: Output:
vuser_init.c(11): 7.23
