What am I doing wrong?
How did you set it? There are like billions of different NaNs. I'm
not sure if isnan checks for all of them. (I'm also not sure that it
doesn't, the docs don't specify.)
you might try using std.math.isNaN instead and see what it does.
Incidentally, I just recently submitted a PR to fix this.
What probably happened is that you're referring to a limited `isnan`
method defined as a unittest utility method in object.d that should
have been private but wasn't.
You want to use `isNan` instead.
Thank you. Unfortunately:
import std.math;
...
assert (isNan (c.curActivation), "cell has unexpected
curActivation: %s".format(c.curActivation));
yields:
cell.d(292): Error: undefined identifier 'isNan', did you mean
overloadset 'isnan'?
while:
import std.math;
...
assert (std.math.isnan (c.curActivation), "cell has unexpected
curActivation: %s".format(c.curActivation));
yields:
core.exception.AssertError@cell.d(310): cell has unexpected idno:
636144943519357244
That is, indeed, an unexpected value, unless it's some representation of
Nan, in which case it should have passed the assert. I notice that it
doesn't appear to be a float, which puzzles me.
