Abs, Exp, Ln, Power, and Sqrt functions in PowerApps
Calculates absolute values, natural logarithms, square roots, and the results of raising e or any number to specified powers.
The Abs function returns the non-negative value of its argument. If a number is negative, Abs returns the positive equivalent.
The Exp function returns e raised to the power of its argument. The transcendental number e begins 2.7182818...
The Ln function returns the natural logarithm (base e) of its argument.
The Power function returns a number raised to a power. It is equivalent to using the ^ operator.
The Sqrt function returns the number that, when multiplied by itself, equals its argument.
If you pass a single number, the return value is a single result based on the function called. If you pass a single-column table that contains numbers, the return value is a single-column table of results, one result for each record in the argument's table. If you have a multi-column table, you can shape it into a single-column table, as working with tables describes.
If an argument would result in an undefined valued, the result is blank. This can happen, for example, with square roots and logarithms of negative numbers.
Abs( Number )
Exp( Number )
Ln( Number )
Sqrt( Number )
- Number - Required. Number to operate on.
Power( Base, Exponent )
- Base - Required. Base number to raise.
- Exponent - Required. The exponent to which the base number is raised.
Abs( SingleColumnTable )
Exp( SingleColumnTable )
Ln( SingleColumnTable )
Sqrt( SingleColumnTable )
- SingleColumnTable - Required. A single-column table of numbers to operate on.
|Abs( -55 )||Returns the number without the negative sign.||55|
|Exp( 2 )||Returns e raised to the power of 2, or e * e.||7.389056...|
|Ln( 100 )||Returns the natural logarithm (base e) of the number 100.||4.605170...|
|Power( 5, 3 )||Returns 5 raised to the power of 3, or 5 * 5 * 5.||125|
|Sqrt( 9 )||Returns the number that, when multiplied by itself, results in 9.||3|
The examples in this section use a data source that's named ValueTable and that contains this data:
|Abs( ValueTable )||Returns the absolute value of each number in the table.|
|Exp( ValueTable )||Returns e raised to the power of each number in the table.|
|Ln( ValueTable )||Returns the natural logarithm of each number in the table.|
|Sqrt( ValueTable )||Returns the square root of each number in the table|
