IS_FINITE

Returns TRUE if the argument is finite, and FALSE otherwise. Only REAL and DOUBLE PRECISION types can represent infinity in Firebolt, meaning that IS_FINITE will always return TRUE for NUMERIC inputs.

Syntax

IS_FINITE(<value>);

Parameters

Parameter	Description	Supported input types
<value>	The input that will be checked to determine if it is a finite number.	NUMERIC, DOUBLE PRECISION, REAL

Return Type

IS_FINITE returns a value of type BOOLEAN.

Examples

Example

The following code example checks whether the value inf, after being cast to a DOUBLE PRECISION data type, is a finite number:

SELECT
    IS_FINITE('inf'::DOUBLE PRECISION);

Returns

The previous code example returns FALSE because infinity is an infinite value.

Example

The following code example checks whether the value 10, after being cast to a REAL data type, is an infinite number:

SELECT
    IS_FINITE(10::REAL);

Returns

The previous code example returns TRUE because 10 is a finite value.
