wish of those help You can multiply a single or double precision float by 2^n just by adding n to the exponent, but for any other multiplier value you'll be changing the mantissa too, and that is obviously going to be nontrivial.

Is it correct to compare the modulo of two double values with an integer in Java?

fixed the issue. Will look into that further As mentioned in other answer, you should compare it with small value rather than an integer, the reason is: Consider there two values: 1.0 and 0.1. If you do 1.0 % 0.1, it will give 0.09999999999999995, as the result of a rounding error. So here if you are comparing with Integer, it will return false. code :
Math.abs(val1 % val2) < EPSILON //where EPSILON is a small value

With these it helps I am trying to manually implement multiplication between a double and a 128 bit integer that I have created myself using two ulongs. , what I am getting wrong here? code :
1234567890123456
1361129467683753 853853498429727072.845824  perceived product
1361129467683753 853853498429727072  perceived rounded product
1361129467683753 792259819967610881  product seen.
1361129467683753 792259819967610880.0

fixed the issue. Will look into that further In a simple way, i have an array of 10 values for example..and i would like to multiply each value with 5. Can i actually just do the following? , This is perfectly fine.
