What does 'smart mode' do?
Smart mode uses regex to find all numbers in the input text, regardless of surrounding words. Example: 'The 3 items cost $50 each, total $150' → numbers found: 3, 50, 150 → sum = 203.
Does this support decimals and negatives?
Yes. Both positive/negative decimals are supported. Example: '-5.5, 10.2' → sum = 4.7.
