Converting Numbers to Strings

You already know that you can use variables in your macros and that there are two very basic types of variables: string variables (containing characters) and numeric variables (containing numeric values). You can quickly and easily convert a number into a string. This is done with the Str() function. The syntax for using this function is:

A = Str(B)

In this syntax, if B is a numeric value equal to 5, then when completed, the string in A will be " 5"; if B is -4, then A would be "-4". Notice the leading space when converting positive numbers. This may not provide satisfactory results for some subroutines. Instead, you should create a function that returns a stripped-down version of the string. The following function does just that:

Function ToNum(X as Variant) as String
    Dim A as String

    A = Ltrim(Str(X))
    ToNum = A
End Function

The reason that the value passed to the function (X) is defined as a Variant is that you can then pass any type of numeric value.
