Any numeric operand in the operation is converted into a 32 bit number. The result is converted back to a JavaScript number. The examples above uses 4 bits unsigned examples. But JavaScript uses 32-bit signed numbers. Because of this, in JavaScript, ~ 5 will not return 10. It will return -6. Computer Science. Computer Science questions and answers.
