EXP Function (DAX)
How does the EXP function (DAX) work?
The EXP function (DAX) returns e raised to the power of a given number. The constant e equals 2.71828182845904, the base of the natural logarithm.
EXP Formula Syntax
EXP(
<number>
)
How do you use the EXP function?
The EXP function finds the value of the constant e raised to a given number, so you can think of the EXP function as e^(number), where e ≈ 2.718. The exponential function can be used to get the value of e by passing the number 1 as the argument.
