i've doing some research on nim high precision resources, my goal is working 
with f1024 numbers,

coded an almost direct c long double wrapper f128 useful for some cases: 
<https://github.com/rforcen/nim/blob/main/ld.nim>

and also hpa wrapper (real+complex) for f1024 and beyond,

hpa enables setting **fixed precision** in Makefile variable,

MANTSIZE_MACRO= -DXMANTISSA_SIZE=62 (default 7) in GNUmakefile

<https://github.com/rforcen/nim/blob/main/hpa.nim>

next step is working with GMP/mpfr as a fast and proven solution that lets you 
set **dynamic precision**

is there any other alternative?
