Yeah, I think Math would have been less surprising. I don't feel strongly, but Number.prototype wasn't what I had expected. >> >> 2) Is it intentional that Number.toInteger(Infinity) returns true? >Huh?

Per your quoted section, toInteger(Infinity) is Infinity, so isInteger(Infinity) is true. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
