FIX: CSng Converted to CDbl for String Literals and Variables

The information in this article applies to:

• Standard and Professional Editions of Microsoft Visual Basic for Windows, version 3.0

SYMPTOMS

Code using the function CSng() within Visual Basic is automatically converted to a CDbl by the compiler.

CAUSE

If a string literal, such as 1.1, or a string variable is placed inside of the CSng function, Visual Basic converts the function to CDbl. The following code demonstrates the problem: Dim S As Single S=CSng("1.1")

When you run a program containing this code, Visual Basic changes it to this code:

   Dim S As Single S=CDbl("1.1")

WORKAROUND

To work around the problem, use another function that operates on the string. Then place this result inside the CSng function. For example, use this:

   S=CSng(Val("100"))

STATUS

This bug was corrected in Microsoft Visual Basic version 4.0 for Windows.
