Syntax
CSng(expression)
The expression argument is any valid 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-precision or
single-precision arithmetic in cases where currency or integer arithmetic normally
would occur.
Use the CSng function to provide internationally aware conversions from any
other data type to a Single subtype. 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 subtype, an error occurs.
The following example uses the CSng function to convert a value to a Single:
related toDim MyDouble1, MyDouble2, MySingle1, MySingle2 ' MyDouble1, MyDouble2 are Doubles.
MyDouble1 = 75.3421115: MyDouble2 = 75.3421555
MySingle1 = CSng(MyDouble1) ' MySingle1 contains 75.34211.
MySingle2 = CSng(MyDouble2) ' MySingle2 contains 75.34216.
