EXP (SSIS)
SQL Server 2005
Returns the exponent to base e of a numeric expression. The EXP function complements the action of the LN function and is sometimes referred to as the antilogarithm.
The numeric expression is cast to the DT_R8 data type before the exponent is computed. For more information, see Integration Services Data Types.
The return result is always a positive number.
