It should overflow computers integer boundary by definition. Jan 14 comment Find modulo of multiplication of two number? I'll do that for sure. But I want to know how to achieve it after computing $\pmod m$ Jan 14 asked Find modulo of multiplication of two number? Dec 24 awarded Nice Question Dec 23 comment What do you call numbers such as 100, 200, 500, 1000, 10000, 50000 as opposed to 370, 14, 4500, 59000 @Henry Could you tell me what is the range of x? I wrote a program to generate those numbers. But I see all are negative and floating point. It was actually obvious as $-x^3$ in the equation Dec 23 comment What do you call numbers such as 100, 200, 500, 1000, 10000, 50000 as opposed to 370, 14, 4500, 59000 @DavidMurdoch In our culture, we dont tip!
