AI-generated Key Takeaways
-
Number.toInt()casts the input value to a signed 32-bit integer with a range of [-2147483648, 2147483647]. -
Casting a floating point number to an integer loses decimal precision.
-
Numbers outside the signed 32-bit integer range are cast to the range's min or max value.
