Introduction

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

The generated API reference for this pilot module is available in
[the Sphinx API section](/stdlib/doc/api/stdlib_kinds.rst).

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
