Syntax

     Dim result As Double = Val(expression) 

or

     Dim result As Integer = Val(charExpression) 

expression (required; String or Object)

Any string representation of a number

charExpression (required; Char)

Any valid character

Description

The Val function converts a string or object representation of a number to the Double data type. A second variation converts a Char data type to its Integer equivalent.

Usage at a Glance

• Only digits at the start of the string expression are examined for conversion; conversion stops at the first nonnumeric character. All whitespace is removed before conversion. An empty string converts to zero.

• &O and &H (the octal and hexadecimal prefixes) are recognized by the Val function.

• Currency symbols, such as $ and £, and delimiters, such as commas, are not recognized by the Val function.

• The Val function only recognizes the period (.) as a decimal delimiter; regional settings are ignored.

• The conversion functions, such as the CDbl function, consider regional settings.
