CSng Function
Returns an expression that has been converted to a Variant of subtype
Single.
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: Dim 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.
