Known type coercion rules:
null * 3 == #@!$
— Any statement that begins with `null` is a compiler error, but this may change in the future.
(null)
is okay though.
3 * null == 0
— Multiplying by null yields 0.
3 / null == Infinity
— In division, null acts a lot like `0`.
3 + "3" == "33"
— If an expression contains a string, the entire expression will be coerced into a string.
"3" * 5 == "33333
— Multiplying a string by a number will replicate the string.
"1234" / 2 == "12"
— Dividing a string by a number will divide the length, then take a substring.
1/0 == "INF" | "Infinity"
— All numerical math is done according to standard IEEE floating-point rules, including well-defined behavior for Inf and NaN. However, conversion of Inf and NaN to a string is undefined (implementation-dependent).
