module platform_mod¶

Overview¶

platform_mod is a module that provides public entities whose value may depend on the operating system and compiler.

The combination of operating system and compiler is referred to here as the platform. platform_mod provides:

integer, parameter :: r8_kind, r4_kind, &
                      c8_kind, c4_kind, &
                      l8_kind, l4_kind, &
                      i8_kind, i4_kind, i2_kind

by use association. These are set to the appropriate KIND values that provide 4 and 8-byte versions of the fortran intrinsic types. The actual numerical value of the KIND may differ depending on platform.

These should be used when the actually bytelength of the variable is important. To specify numerical precision, Fortran recommends the use of the intrinsics SELECTED_REAL_KIND and SELECTED_INT_KIND.
