Converts an expression to a Single.
CSng(expression)
The expression argument is any valid numeric or string expression.
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.
Data Type Summary.
This example uses the CSng function to convert a value to a Single.
' MyDouble1, MyDouble2 are Doubles.= 75.3421115: MyDouble2 = 75.3421555= CSng(MyDouble1) ' MySingle1 contains 75.34211.= CSng(MyDouble2) ' MySingle2 contains 75.34216.
