Summary0007896: [IEEE 754] OCaml does not enable rounding direction to be specified by programs
DescriptionSome floating-point computations require rounding direction to be specified (typically to obtain safe bounds). However OCaml does not support directly this feature, so external functions have to be written (see attached code).
Steps To ReproduceCompile files in archive with:
ocamlc -c roundingMode_stubs.c
ocamlc -c roundingMode.mli
ocamlc -c
ocamlc -custom roundingMode.cmo roundingMode_stubs.o

TagsNo tags attached.

I'm not an expert on IEEE754, but it sounds like a potentially useful addition. Would you like to open a PR on [^] to discuss your code?
