* DESCRIPTION
* The ase_awk_valtonum() function converts a value to a number.
* The converted value is stored into the variable pointed to by
* either l or r depending on the type of the number. If the value
* is converted to a long number, the function returns 0 and l is
* set with the converted number. If the value is converted to a real number,
* the function returns 1 and r is set with a real number.
* If the value is converted to a long number, it is stored in the memory
* pointed to by l and 0 is returned. If the value is converted to a real
* number, it is stored in the memory pointed to by r and 1 is returned.
*
* RETURN
* The ase_awk_valtonum() function returns -1 on error, 0 if the converted
* value is a long number and 1 if it is a real number.
* number is a long number and 1 if it is a real number.
*
* EXAMPLES
* ase_long_t l;
