Syntax
EXP(argument)
Required Argument
argument
specifies a numeric constant, variable, or expression. For more information, see Definitions for SAS Expressions in SAS Language Reference: Concepts.
Details
The EXP function raises the constant e, which is approximately 2.71828, to the power that is supplied by the argument. The result is limited by the maximum value of a floating-point value on the computer.
Example
The following SAS statements produce these results.
SAS Statement  Result  
x=exp(1.0);
2.7182818285

x=exp(0);
1

已解决，谢谢指点！
