Is there any way.. that I can pass a double from C to ocaml without loosing
precision?
What is the data type that is equivalent to double in Ocaml.
I'm trying to get a double from a C-function and convert it to "Num" in
Ocaml.
Thank you.

The OCaml "float" value is actually double precision. From the manual:
Floating-point numbers
Floating-point values are numbers in floating-point representation. The
current implementation uses double-precision floating-point numbers
conforming to the IEEE 754 standard, with 53 bits of mantissa and an
exponent ranging from -1022 to 1023.
