Note that using long doubles everywhere
would slow down a memory bound computation.
Fetching more data would be required.

One might introduce glp_double_t.
C99 uses double_t for the type in which unnamed
intermediate results of double calculations are stored.

Use glp_double_t for locals that are not arrays,
especially running totals.
Do the casts to ensure that desired calculations
are actually done in glp_double_t.
