isNaN(X) where X is greater than e9e15 return true

[1e1000000]

Expected result:

isNaN("ee16")
false

Actual result:

isNaN("ee16")
true

I seem it most likely because break_infinity.js

isNan is a built in function, I didn't write it, and "ee16" is indeed not a number. maybe you mean this?

Decimal.fromString("ee16").toNumber()
Infinity
isNaN(Decimal.fromString("ee16").toNumber())
false

[1e1000000]

For actual result, it return true instead

[Patashu]

isNaN("ee2") is also true. Try it
