Numeric literal example:

D code

derive type:single value: EXP(1)

Output: Generates a column containing the value of e1, which is approximately 2.718281828.

Column reference example:

D code

derive type:single value: EXP(MyValue) as: 'exp_MyValue'

Output: Generates the new exp_MyInteger column containing the value of e to the power of the value in the MyValue column. 

D s

D code

derive type:single value: EXP(numeric_value)
