Another example of your belief in the programming language as pixy dust theory.

I have seen inaccurate, poorly written numerics Fortran code,
and accurate well written numerics C code (and other languages).

Using a language thought to have some desirably characteristic
does not mean that the code written has this characteristic.

Languages do not come with a sachet of pixy dust to sprinkle on the code.
