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.

Syntax

Linux and 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.
Alternate Options
None

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
