core.math.rndtonl: invalid return type or description?

[ketmar via Digitalmars-d]

core.math.rndtonl is declared as this:

	extern (C) real rndtonl(real x);

yet it's description says: "...If the integer value of x is greater than 
long.max, the result is indeterminate."

it looks like it either should return `long`, or this part of description 
was copypasted from `rndtol`. and if it *really* has such limitation, but 
returns `real`, i think it should be clarified in documentation, 'cause 
right now it is somewhat confusing.
