FLOAT32

This function is used to cast data to the FLOAT32 data type.

Syntax

FLOAT32 ( arg )  

arg
The value to be cast. The value has to be of a Numeric or Date & Time data type category.

Return Value

Returns the FLOAT32 representation of the value provided.

Remarks

  • If the value falls outside of the FLOAT32 range, an overflow error is returned.
  • Date & Time values are first converted to their underlying unix representation before being converted.

Examples

This returns the FLOAT32 representation of -1. Without data type context, numeric values are interpreted as their largest datatype. In this example, because -1 is signed it's interpreted as an INT64.

SELECT FLOAT32(-1);

Response:

FLOAT32(-1) [FLOAT32]
-1.0
