> What does --with-precision=extended?
It sets the default precision of real and complex floats (kind type parameter)
to 80 bit instead of 64 bit (double) or 128bit (quadruple) precision according
to:
!!! available REAL kinds ! prec. ! ISO ! C
integer, parameter :: single = 4 ! 1.. 6 ! real32 ! c_float
integer, parameter :: double = 8 ! 7..15 ! real64 ! c_double
integer, parameter :: extended = 10 ! 16..18 ! real128 ! c_long_double
integer, parameter :: quadruple = 16 ! 19..33 ! -1 ! c_float128
integer, parameter :: default = extended
