Description

If a number is outside of 2.2250738585072014E-308 to 1.7976931348623158E+308 range, PHP converts it to -INF or INF.

Values INF, -INF and NAN are considered float in PHP as for the is_float function.

The Type constraint relies in this function to check for a valid float.

Now, are this valid float numbers? IMHO no.

FTR: this doesn't happen with integers, as PHP converts them to float once they go outside the PHP_INT_MIN and PHP_INT_MAX range...

How to reproduce

var_dump(is_float(INF));
var_dump(is_float(NAN));

Possible Solution

Add an extra check for is_finite, when dealing with floats?
