Thanks, that was the clue I needed. -Walter

Yes, I did. I think this is a problem peculiar to my system (or me). Since I don't see anybody else reporting trouble with this.

(dmd 0.64 on Win32)

void main() {
    double d;
    printf('%f',d.isnan);
}

I get: no property 'isnan' for type 'double'. The same happens when using float or real, or for isinfinite, isnormal. I thought this was already implemented.

By the way, maybe this a language (english) issue, but why this inconsistency: float.infinity and float.isinfinite?

That's done with math.isnan(d).

There isn't a float.isinfinite. float.infinity does not return a true or false, but returns the infinity value.

Then the docs need to be fixed.

What I meant with the inconsistency between isinfinite and infinity is that the first ends with e and the other with y. That's why I said it might be that just english is that way, but it's kinda confussing.

Ignore that second part I said. I was too tired to read well.

What I wanted to know is if I do

if (cond)
    d=double.infinity
else
    d=someOtherValue;

How do I check if d is infinity or not?

Yes, I discovered it after my post. Thanks.
