Description
Converts an expression to a Single.
Syntax
CSng(expression)
The expression argument is any valid numeric or string expression.
Remarks
In general, you can document your code using the data type conversion functions to show that the result of some operation should be expressed as a particular data type rather than the default data type. For example, use CDbl or CSng to force double- or single-precision arithmetic in cases where currency or integer arithmetic normally would occur.
You should use the CSng function instead of Val to provide internationally-aware conversions from any other data type to a Single. For example, different decimal separators are properly recognized depending on the locale setting of your system, as are different thousand separators.
If expression lies outside the acceptable range for the Single data type, an error occurs.

Example
This example uses the CSng function to convert a value to a Single.
' MyDouble1, MyDouble2 are Doubles. MyDouble1 = 75.3421115 : MyDouble2 = 75.3421555 MySingle1 = CSng(MyDouble1) ' MySingle1 contains 75.34211. MySingle2 = CSng(MyDouble2) ' MySingle2 contains 75.34216.
