Discussion
The get_xarg_fval function gets a subroutine argument and converts it into a floating-point value of the native C “double” type.
The return value is the referenced argument evaluated as a double. If the argument wasn’t passed, the returned value is zero. If the argument is alpha, it is treated as if it were decimal.
