%intoffloat converts Infinity and NaN to 0

[glennsl]

This caught me by surprise. I expected it would raise an exception, similar to div by zero.

Is this behavior correct? If so, what is the rationale for it?

Repro:

int_of_float(infinity)
// or
int_of_float(nan)

I suppose the rationale can be given by the conversion function defined by EMCA-262 (i.e. The JavaScript language specification). This seems like the most natural and likely most performant conversion, given ReScript's goal of seamless integration with JavaScript.

I'll consider the issue resolved based on this.
