Math.clz32(0) Equals 32

πŸ“– Usage Example
// Count leading zero bits in a 32-bit integer
Math.clz32(1)   // β†’ 31
Math.clz32(4)   // β†’ 29

Use Math.clz32() to count leading zero bits of a 32-bit integer, useful in low-level bitwise optimizations.

Math.clz32(x)

Math.clz32(0) returns 32 because all 32 bits are zero.

Challenge: Verify the leading zero count for 0.

πŸ’‘ Hints (2)
  • β€’ All 32 bits of 0 are zero
  • β€’ This is the maximum possible return value of clz32
