Intel® Fortran Compiler 17.0 Developer Guide and Reference
Specifies the default KIND for DOUBLE PRECISION and DOUBLE COMPLEX declarations, constants, functions, and intrinsics.
Linux and macOS: | -double-size size |
Windows: | /double-size:size |
size |
Specifies the default KIND for DOUBLE PRECISION and DOUBLE COMPLEX declarations, constants, functions, and intrinsics. Possible values are: 64 (KIND=8) or 128 (KIND=16). |
64 |
DOUBLE PRECISION variables are defined as REAL*8 and DOUBLE COMPLEX variables are defined as COMPLEX*16. |
This option defines the default KIND for DOUBLE PRECISION and DOUBLE COMPLEX declarations, constants, functions, and intrinsics.
Option |
Description |
|---|---|
double-size 64 |
Defines DOUBLE PRECISION declarations, constants, functions, and intrinsics as REAL(KIND=8) (REAL*8) and defines DOUBLE COMPLEX declarations, functions, and intrinsics as COMPLEX(KIND=8) (COMPLEX*16). |
double-size 128 |
Defines DOUBLE PRECISION declarations, constants, functions, and intrinsics as REAL(KIND=16) (REAL*16) and defines DOUBLE COMPLEX declarations, functions, and intrinsics as COMPLEX(KIND=16) (COMPLEX*32). |
The real-size option overrides the double-size option; for example, on Linux* systems, "-double-size 64 -real-size 128" acts like "-double-size 128 -real-size 128".
