I need some division algorithm which can handle big integers (128-bit). I've already asked how to do it via bit shifting operators. However, my current implementation seems to ask for a better approach
Basically, I store numbers as two long long unsigned...

You shouldn't be using long double for your "normal divisions" but integers there as well.

Hello everyone,
I recently came across a problem that sparked my curiosity. Try to solve this problem using long division w/ decimals instead of remainders, solving to 4 decimal places. After you have done that, use long division w/ remainder. Finally...

I have two unsigned long longs X and Y, where X < Y, but both may be very large. I want to compute the first digit past the decimal point of X / Y. For example, if X is 11 and Y is 14, then 11 / 14 is .785…, so the result should be 7.
(X * 10) / Y ...

This should round down the numbers and drop any extra decimals.

I'm erring because the whole number cumulative total is greater than
the long data type.
Any suggestions on how to handle in VB?

I am considering writing two limited precision alternatives to BigDecimal, namely DecimalInt and DecimalLong. These would be capable of dealing with numbers within the real bounds of int and long with an arbitrary number of decimal places, creatable in...

For handling money, then this is usually done by holding integer (long if necessary) numbers of cents.

I receive an integer that represents a dollar amount in fractional denominations. I would like an algorithm that can add those numbers without parsing and converting them into doubles or decimals.
For example, I receive the integer 50155, which means ...

This problem does not require a calculator or long division, just moving units around.
That 20 petabytes are used by a search engine every day of the week, how long does it take this search.
