=====atof=====
Syntax:

<code>
    #include <cstdlib>
    double atof( const char *str );
</code>
The function atof() converts str into a double, then returns that value. str
must start with a valid number, but can be terminated with any non-numerical
character, other than "E" or "e". For example,

<code>
     x = atof( "42.0 is the answer" );
</code>
results in x being set to 42.0.
