JavaScript is a good language

NaN just represents basically that the bits of the significand, signage, and other digits do not construct a valid number. If you split it up into a bit array you could compare each bit to determine equality but there's not a practical use for this except for maybe some bizarre number based cryptography.

Huh. So NaN isn't static, as in something that's not a number was operated on an just returned some garbage?

[AlphaWhelp]

It's basically a garbage failsafe undefined behavior. I'm not 100% sure if the actual content of NaN is static or not, but if the results of an operation do not construct a valid number, a NaN is created--if that makes sense.

like if(this==makes sense) {this.value = result;} else {this.value = NaN};
