SQRT

Returns the positive square root of a given number.

Use

SQRT(number) and replace number with the field or expression you want computed into a square root.

Calculating the square root of a negative number results in an error on the detail page.
Avoid division by zero errors by including an IF function such as: IF(Amplitude__c >= 0, SQRT(Amplitude__c), null).

Square Root Example

SQRT(25) returns the square root of 25, which is 5.

Amplitude Example

SQRT(Amplitude__c) returns the square root of a custom number field representing the amplitude of an earthquake.
