SQRT

Returns the square root of a non-negative numeric value.

Syntax

SQRT( numeric_value )

Argument	Required/ Optional	Description
numeric_value	Required	Positive numeric value. Passes the values for which you want to calculate a square root. You can enter any valid expression.

Return Value

Double value.

NULL if a value passed to the function is NULL.

Example

The following expression returns the square root for the values in the NUMBERS column:

SQRT( NUMBERS )

NUMBERS	RETURN VALUE
100	10
-100	None. Data Integration writes the row into the error rows file.
NULL	NULL
60.54	7.78074546557076

The value -100 results in an error during the session, since the function SQRT only evaluates positive numeric values. If you pass a negative value or character value,

Data Integration

writes the row into the error rows file.

You can perform arithmetic on the values passed to SQRT before the function calculates the square root.
