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.
