Syntax

     Dim result As String = Hex(number) 

number (required; numeric or string value)

A number, or a string that can be interpreted as a number. Nonintegral numbers are rounded before conversion.

Description

The Hex function returns a string that represents the hexadecimal value of a numeric expression.

Usage at a Glance

• Nonintegral numbers are rounded before conversion to hexadecimal format. An Empty value results in "0." A value of Nothing generates an error.

• The hexadecimal result is limited to 16 digits. Numbers larger than this limit result in an overflow error.

• If the source value is a string, it may appear in hexadecimal format. Such strings begin with the standard "&H" hexadecimal prefix for Visual Basic, as in "&H10" for a decimal value of 16.

Version Differences

The Visual Basic 6 version of the Hex function only handled up to eight hex digits. The .NET version handles up to 16 digits.
