Math.clz32()

The Math.clz32() static method returns the number of leading zero bits in the 32-bit binary representation of a number.

If x is not a number, it will be converted to a number first, then converted to a 32-bit unsigned integer.

If the converted 32-bit unsigned integer is 0, 32 is returned, because all bits are 0. If the most significant bit is 1 (i.e., the number is greater than or equal to 231), 0 is returned.

This function is particularly useful for systems that compile to JS, like Emscripten.

Return value: The number of leading zero bits in the 32-bit binary representation of x.

Syntax example: Math.clz32(x)
