benchmark_kinds

Definition

Provides constants for defining standard integer and real values.

Examples

The following example demonstrates some of the constants found in the benchmark_kinds module.

real(r8) a      :: 0_r8
integer(i4) i  :: 1_i4 

Remarks

The constants are coming from the intrinsic module iso_fortran_env. If the compiler does not provide such intrinsic module then the compilation will fail.

Parameters
integer, parameter, public	i1 = int8
	8-bit integer constant deriving from the int8 intrinsic constant of the iso_fortran_env module
integer, parameter, public	i2 = int16
	16-bit integer constant deriving from the int16 intrinsic constant of the iso_fortran_env module
integer, parameter, public	i4 = int32
	32-bit integer constant deriving from the int32 intrinsic constant of the iso_fortran_env module
integer, parameter, public	i8 = int64
	64-bit integer constant deriving from the int64 intrinsic constant of the iso_fortran_env module
integer, parameter, public	r4 = real32
	single precision, 32-bit real constant deriving from the real32 intrinsic constant of the iso_fortran_env module
integer, parameter, public	r8 = real64
	double precision, 64-bit real constant deriving from the real64 intrinsic constant of the iso_fortran_env module
integer, parameter, public	r16 = real128
	quadruple precision, 128-bit real constant deriving from the real128 intrinsic constant of the iso_fortran_env module
