minFloat — Return the minimum supported positive floating-point value
Always returns the same value, the smallest supported positive floating-point value.
The exact value varies from implementation to implementation. Some return the smallest normalized value (the smallest value that can be represented without losing precision); others return the smallest possible value (where precision is lost but there really is no number smaller).
This ambiguity is permitted by the specification of this function: the only thing guaranteed is that the value is less than or equal to the smallest normalized positive floating-point value, which is 1.17549435e-38 for WMLScript.
returns a floating-point number less than or equal to
