Parameters
- cExpression
- Specifies a character expression composed of up to 16 numbers. Rounding occurs if more than 16 numbers are included in cExpression. If the first character of cExpression is a dollar sign ($),VAL( ) returns a currency value. In all other situations VAL( ) returns a numeric value.
Return Value
Numeric or Currency data type. VAL( ) returns the numbers in the character expression from left to right until a non-numeric character is encountered. Leading blanks are ignored. VAL(В ) returns 0 if the first character of the character expression is not a number, a dollar sign ($), a plus sign (+), or minus sign (-). You can control the result of VAL(В ) by issuing the SET DECIMALS command before using the VAL(В ) function.
