Amount Splitter takes one total and cuts it into several shares while guaranteeing that the shares still add back up to exactly that total - handy for splitting a bill, handing out red packets, apportioning a cost by ratio, or spreading a budget across line items.

Three modes:
· Equal split - every share is the same, ideal for splitting a bill. When the total does not divide evenly there is a remainder, and the Remainder setting decides who takes it;
· By ratio - put one weight per line (or separate them with spaces or commas) in the box on the left, e.g. 2 3 5. That produces 3 shares worth 20% / 30% / 50% of the total, which suits capital contribution, headcount or floor-area apportioning;
· Random split - shares are random, like a lucky-money handout (random weights are generated and then split proportionally).

The Remainder setting applies to the Equal and By-ratio modes only: Spread across shares (default and fairest - the leftover cents go to the shares with the largest fractional part), Add to last share, Add to first share.

Steps:
1. Enter the Total amount;
2. Pick the Split mode; Equal and Random also need a share count;
3. In By-ratio mode type the weights into the box on the left - their count sets the number of shares;
4. Choose the number of Decimals (2 means to the cent) and the Remainder handling;
5. Click Run. Each share is printed on its own line on the right, and the table below lists the weight, amount and percentage of every share.
Note: to avoid floating point errors (0.1 + 0.2 is not exactly 0.3), every amount is converted to integer cents before splitting and any last-cent difference is settled by the Remainder setting, so the sum shown in the summary always equals the total.
