AI-generated Key Takeaways
-
Number.uint32()casts a number to an unsigned 32-bit integer. -
The method returns a Number type.
-
Casting floating-point numbers to uint32 results in loss of decimal precision.
-
Numbers outside the uint32 range will be clamped to the minimum or maximum value of the range.
