And the list of global constants then would look like this:

global constant
   LN2        = log(2),
   LN10       = log(10),
E          = machine_func(47, {105,87,20,139,10,191,5,64}),    --
   2.7182818284590452e0
   SQRT2      = sqrt(2),
   HALF_SQRT2 = SQRT2/2
PI         = machine_func(47, {24,45,68,84,251,33,9,64}),      --
   3.1415926535897932e0
   HALF_PI    = PI/2
   QUARTER_PI = PI/4
   TWO_PI     = PI*2

I like it. The calculation of the constant values is only done once at
initialization of the program, so the time for it is negligible, no?
