SQL Server EXP() Function
The SQL Server EXP() function returns the value of the mathematical constant e raised to a specified power, which is the exponential value of a given number.
Syntax
EXP(n)
Parameter: n is the exponent value, which can be any number.
Return Value: The function returns e raised to the power of n.
Usage
The SQL Server EXP() function is commonly used to calculate exponential values.
Examples
Here are two examples of using the SQL Server EXP() function:
Example 1
Calculate the square of e:
SELECT EXP(2) as Result;
Result:
| Result |
|---|
| 7.389056 |
Explanation: The function returns the value of e raised to the power of 2, which is approximately 7.389056.
Example 2
Calculate the exponential value of e with different exponents:
SELECT EXP(1) as Result1, EXP(2) as Result2, EXP(3) as Result3;
Result:
| Result1 | Result2 | Result3 |
|---|---|---|
| 2.718282 | 7.389056 | 20.08554 |
Explanation: The function returns the value of e raised to the power of 1, 2, and 3, respectively.
Conclusion
The SQL Server EXP() function returns the exponential value of a given number with respect to e. It can be used to calculate exponential values.
