TO_FLOAT

Converts a string or numeric value to a double-precision floating point number (the Double datatype). TO_FLOAT ignores leading blanks.

Syntax

TO_FLOAT( value )

The following table describes the argument for this command:

Argument	Required/ Optional	Description
value	Required	Must be a string or numeric datatype. Passes the values you want to convert to double values. You can enter any valid transformation expression.

Return Value

Double value.

NULL if a value passed to this function is NULL.

If the value passed to the function contains data that is not valid for a float value, the Data Integration Service marks the row as an error row or fails the mapping.

Example

This expression uses values from the port IN_TAX:

TO_FLOAT( IN_TAX )

IN_TAX	RETURN VALUE
'15.6789'	15.6789
'60.2'	60.2
'118.348'	118.348
NULL	NULL
'A12.3Grove'	Error. Integration Service skips this row.
