What is the maximum value of Nat64, Nat32, Nat16, Nat8, Int64, Int32, Int16, and Int8?

[icme]

Maybe this is the value I’m looking for?

Infinity and NaN

module { public func isNaN(v:Float): Bool { return ((v < 0.000) == false) and ((v > 0.000) == false) }; public func isInfinite(v:Float): Bool { return v > 1.8e307 } } This is the method I wrote to judge NaN and Infinity, what’s wrong with it. . if so. Please point out where I am wrong
