The stdlib_kinds module

Introduction

The stdlib_kinds module provides kind parameters for the Fortran intrinsic data types, integer, logical, real, and complex.

Constants provided by stdlib_kinds

sp

Single precision real kind parameter. Provides real kind parameter for floating point numbers with a minimal precision of 6 significant digits.

dp

Double precision real kind parameter. Provides real kind parameter for floating point numbers with a minimal precision of 15 significant digits.

xdp

Extended double precision real kind parameter. Provides real kind parameter for floating point numbers with a minimal precision of 18 significant digits. If not available it has value -1.

qp

Quadruple precision real kind parameter. Provides real kind parameter for floating point numbers with a minimal precision of 33 significant digits. If not available it has value -1.

int8

Reexported intrinsic named constant int8 from iso_fortran_env.

int16

Reexported intrinsic named constant int16 from iso_fortran_env.

int32

Reexported intrinsic named constant int32 from iso_fortran_env.

int64

Reexported intrinsic named constant int64 from iso_fortran_env.

lk

Kind parameter of the default logical data type.

c_bool

Reexported intrinsic named constant c_bool from iso_c_binding.
