# Directives

FLOATINGPOINT | Switch to Scientific Notation

## Format

FLOATINGPOINT

## Description

Use the FLOATINGPOINT directive to have PxPlus start using scientific notation with all numeric data. In scientific notation, a number is represented as a fraction times 10 to some power (e.g. .nnnnn*10^xx is displayed as .nnnnnExx).

In FLOATINGPOINT mode, no rounding is done on numeric calculations. If the numeric output is unformatted, PxPlus uses scientific notation (e.g. .314159E+01). Use the PRECISION directive to end FLOATINGPOINT mode.

#### Note:
FLOATINGPOINT notation is reset to standard decimal notation during a RESET operation; however, prior to version 5, it was left On.
