atof()

Purpose:

atof() converts an alpha field to a float field, and returns the float field.

Usage:

fval = atof(aval);

Arguments:

alpha aval;

Returns:

float fval;

There are no error returns from this PCL.

Where Used:

atof() can be called from anywhere.

Example:

fl = atof("3.24");

Description:

This PCL takes one alpha argument and converts it to a float, returning the float. A leading or trailing sign can be used. It is possible to get garbage in the return if the alpha argument was garbage also.

Bugs/Features/Comments:

atof() does not verify the format of aval.
