Tool details and privacy
Equal mode needs one name per line. Weight or percent mode is written as the name, a comma, then the number.
100 split equally across three gives 33.34, then 33.33, then 33.33. Percentages must add up to exactly 100.
Options
- In equal mode write a name only. In weight or percent mode write the name, a comma, then the number. The limit is 20 parties.
Limits
- Amounts use two decimal places and up to 12 digits before the decimal point. Rounding is half up.
- 1,250 is rejected. Write 1250 or 1250.50.
- Percentages must equal 100.00. Fewer than two parties is rejected.
