Function/Subroutine Documentation

prec_const_init()

subroutine prec_const_mod::prec_const_init

Initialize prec_const module.

Bug:

The code crashes when correctly initializing nan variable

Here is the caller graph for this function:

Variable Documentation

dp

integer, parameter prec_const_mod::dp = REAL64

Double precision real numbers.

nan_

real(dp), public, protected prec_const_mod::nan_

Not a number.

Used to initialize some arrays and detect problems

Todo:

reactivate its initialization. It had been turned off because the code crashes otherwise.

pi

real(dp), parameter prec_const_mod::pi = 3.141592653589793238462643383279502884197_dp

Pi.

pio2

real(dp), parameter prec_const_mod::pio2 = 1.57079632679489661923132169163975144209858_dp

Pi/2.

sqrt2

real(dp), parameter prec_const_mod::sqrt2 = 1.41421356237309504880168872420969807856967_dp

Sqrt(2)

stderr

integer, parameter prec_const_mod::stderr = error_unit

Standard error unit.

stdin

integer, parameter prec_const_mod::stdin = input_unit

Standard input unit.

stdout

integer, parameter prec_const_mod::stdout = output_unit

Standard output unit.

twopi

real(dp), parameter prec_const_mod::twopi = 6.283185307179586476925286766559005768394_dp
