Hi,
I just stumbled across these 2 lines in RealFromComplex (lines 208 & 209
in src/main/coerce.c):
double attribute_hidden
RealFromComplex(Rcomplex x, int *warn)
{
if (ISNAN(x.r) || ISNAN(x.i))
return NA_REAL;
if (ISNAN(x.r)) return x.r;
<- line 208
if (ISNAN(x.i)) return NA_REAL;
<- line 209
if (x.i != 0)
*warn |= WARN_IMAG;
return x.r;
}
They were added in 2015 (revision 69410).
They don't serve any purpose and might slow things down a little (unless
compiler optimization is able to ignore them). In any case they should
probably be removed.
Cheers,
H.
