The $UNFLOAT function converts a floating-point number from the standard IBM floating point format to the corresponding character string representation. <var class="product">Model 204</var> maintains 15 significant decimal digits of precision for 8-byte floating-point numbers and 6 significant digits of precision for 4-byte floating-point numbers. For an expanded discussion of rounding numbers, please refer to [[Floating Point Conversion, Rounding, and Precision Rules#Mapping and precision adjustment|Mapping and precision adjustment]].
Syntax
The format of the $UNFLOAT function is: 
$UNFLOAT(number)

where number can be either four bytes for a single-precision floating-point number or eight bytes for a double-precision floating-point number.
$UNFLOAT converts floating-point numbers from the internal form used by <var class="product">Model 204</var> for storage efficiency to a printable string. $UNFLOAT also allows the manipulation of these numbers by User Language.
Example
For example, the result of the expression:
$UNFLOAT($FLOAT('1.234'))

is the string 1.234. If the string argument is omitted or invalid, a null string is returned.
