FAQ
- What is the weight setting in proportional distribution?
- It represents the relative ratio between elements. If you set weights A=3, B=2, C=5, the total amount splits into 30%, 20%, and 50% shares.
- How does the calculator prevent division-by-zero errors?
- If you input a base value of 0, the engine normalizes the output to 0% to avoid runtime equation errors.
