Requirements for this Issue

The source code in this issue is designed for all versions of Visual Basic.

In this Issue

This issue shows how to convert a fractional value into a decimal value. The function will take number that contains a fraction, such as 40 1/4 and convert it to 40.25. This is useful in any application where the input might involve fractions, such as building material measurements, stocks, and math tests (of course there are many more applications).


Public Function FractionValue(ByVal sFraction As String) As Double


Return Value

None unless an error occurs. If an error occurs it will be raised to the caller.

Sample Usage

The below example uses the FractionValue to convert several numbers into the decimal equivalents.

       Dim dNumber1 as Double
       Dim dNumber2 as Double

       dNumber1 = FractionValue("40 1/4")
       dNumber2 = Fractionvalue("1 1/2")

dNumber1 will be equal to 40.25 and dNumber2 will be equal to 1.5.
