Is rndtonl a Digital Mars C thing?
yes, it looks like DMC library function. thus, is should be versioned out
on non-DMC builds. another bug. ;-)
It has no implementation in druntime, and I get an undefined reference
when I try to call it on Linux.
It compiles on Windows (wine, -m32), but only ever returns -nan.
If this is the same function:
<http://www.digitalmars.com/rtl/fltpnt.html#rndtol>, then it should
return a C long, which I guess is a D int on 32 bits. And surprise: that
works.
no, there is `rndtol()` and `rndtonl()` in `core.math`, they are different
functions.
also, `rndtol()` should return D `long` (i.e. 64 bit value). at least this
is what `core.math` says.
