# System Variables

PRC | Precision Currently in Effect

Numeric System Variable

## Contents

Integer, current PRECISION

## Description

The PRC variable contains a numeric value (integer) that indicates the current PRECISION in effect (except in scientific notation). This value will be in the range -1 to 18. The default is 2 (two digits to the right of the decimal point).

If the mode is FLOATINGPOINT, then the value returned is in scientific notation. Either a PRECISION -1 statement or a FLOATINGPOINT directive will activate scientific notation. The PRECISION directive cancels it.
