Lines 10 to 15 in a96663b

    
           exports.intMul = function (x) { 
        
             return function (y) { 
        
               /* jshint bitwise: false */ 
        
               return x * y | 0; 
        
             }; 
        
           };

I can't believe this was never mentioned as an issue before.

Maybe replace this with Math.imul?

My bad.

Closing as duplicate (but I think it might have fit here more...)

No worries, it's split between both! 🙂

The numeric operations are inlined by the compiler where it can (kinda, the compiler produces code equivalent to their implementation here, it doesn't technically inline since it doesn't look at the JS implementation of them).

	exports.intMul = function (x) {
	return function (y) {
	/* jshint bitwise: false */
	return x * y \| 0;
	};
	};
