float

Defines a floating point number in 4 bytes, in the range of 3.4e +/-38 (7 digits). See Type-Specifier for more information.

Example

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
