TO_BINARY_FLOAT

TO_BINARY_FLOAT converts a text or numeric expression to a single-precision floating-point number.

Return Value

BINARY_FLOAT

Syntax

TO_BINARY_FLOAT (expr [, fmt [, 'nlsparam' ] ])

Arguments

n can be any text or numeric expression.

fmt is a text expression that identifies a number format model as described in the Oracle Database SQL Language Reference.

nlsparam specifies the characters used by these number format elements:

This argument has the format shown here:

'NLS_NUMERIC_CHARACTERS = ''dg''
 NLS_CURRENCY = ''text''
 NLS_ISO_CURRENCY = territory '

The d is the decimal character, and the g is the group separator. They must be different single-byte characters. Within the quoted string, use two single quotation marks around the parameter values. Ten characters are available for the currency symbol.

If you omit this argument or any of the NLS parameters, then this function uses the default values for your session to interpret expr.

Examples

All of these examples return the value 1.235E+003:

TO_BINARY_FLOAT(1234.56)

TO_BINARY_FLOAT('$1,234.56', '$9,999.99')

TO_BINARY_FLOAT('1.234,56', '9G999D99', 'NLS_NUMERIC_CHARACTERS='',.''')
