Precisely single is a simple tool for rounding off decimal numbers in a way that their value is not affected when parsed into IEEE 754 single precision number format.
Precisely single tries to reduce the number of digits after the decimal separator as much as possible. It does not try to remove digits before the decimal separator.
Precisely single runs within the Microsoft .NET Framework 2.0. Information about the .NET Framework is available on Microsoft's website http://msdn.microsoft.com/netframework.

Numbers provided as input to Pecisely single must respect the following notation rules (standard decimal notation). Exponential notation is not supported!
Additionally, Precisely single allows you to append a + or - sign to the end of the number to indicate whether the real number's absolute value is slightly higher or lower than the last digit can express. This is only useful when the last digit is 5.
Leading and trailing spaces are ignored.
