NUMVAL-F
The NUMVAL-F function returns the numeric value represented by the alphanumeric character string or national character string specified as the argument. The function removes any leading or trailing spaces in the string to produce a numeric value.
The function type is numeric.
- argument-1
- Must be an alphanumeric literal, a national literal, or a data item of class national or class alphanumeric that contains a character string in the following format:
- space
- A string of one or more spaces.
- digit
- A string of one or more digits.
- n
- A string of one to four digits representing the exponent value.
- E
- If argument-1 is alphanumeric, E must be either an uppercase or lowercase E character.
If the DECIMAL-POINT IS COMMA clause is specified in the SPECIAL-NAMES paragraph, a comma must be used in argument-1 rather than a decimal point.
The returned value is a floating-point approximation of the numeric value represented by argument-1. The precision of the returned value depends on the setting of the ARITH compiler option.
