Math.imul() — 32-bit Overflow

📖 Usage Example

// 32-bit integer multiplication (C-like overflow)
Math.imul(3, 4)    // → 12
Math.imul(-1, 8)   // → -8

Use Math.imul() for fast 32-bit integer multiplication with C-like overflow semantics, useful in hashing or WebAssembly.

Math.imul()

Performs C-like 32-bit integer multiplication.

Challenge: Observe that Math.imul(0xffffffff, 5) overflows to -5 in 32-bit signed integer arithmetic.
