# complex-limited-range, Qcomplex-limited-range

Determines whether the use of basic algebraic expansions of some arithmetic operations involving data of type COMPLEX is enabled. This feature is only available for ifort.

## Syntax

Linux: | -complex-limited-range -no-complex-limited-range

macOS: | -complex-limited-range -no-complex-limited-range

Windows: | /Qcomplex-limited-range /Qcomplex-limited-range-

## Arguments

None

## Default

-no-complex-limited-range or /Qcomplex-limited-range- | Basic algebraic expansions of some arithmetic operations involving data of type COMPLEX are disabled.

## Description

This option determines whether the use of basic algebraic expansions of some arithmetic operations involving data of type COMPLEX is enabled.

When the option is enabled, this can cause performance improvements in programs that use a lot of COMPLEX arithmetic. However, values at the extremes of the exponent range may not compute correctly.
