If you petition Intel to improve support for signaling NaNs, I will gladly sign that petition. Maybe change.org <https://www.change.org/>?
But seriously, this is not a Julia thing. It's the result of a bunch of horse trading between hardware manufacturers and spec designers in the late 70s. You may want to read these: - https://www.cs.berkeley.edu/~wkahan/ieee754status/754story.html - http://www.cs.berkeley.edu/~wkahan/ieee754status/IEEE754.PDF (see page 7 in particular) In short, "signaling NaNs" which is what you want are an optional part of the IEEE 754 standard, not well supported in most hardware, and have performance issues even when they are supported.
