Decimal vs American vs implied %?
Three dialects, one price
Same ticket, three spellings. Decimal is what you get back. American is the US sticker. Implied % is the tax-inclusive chance the shop is selling.

Decimal 1.91 is the European −110. You stake 1, you get 1.91 back if it hits (profit 0.91).
Implied percent is 1 / decimal. It includes juice, so two sides will add to more than 100% unless you peeled it. That peeled number is True.
The converter on Calculators is the decoder ring. Use it once, then you will start seeing all three at once.
takeaway2.00 = +100 = 50%. Longer decimal = greener dog. Fatter minus = heavier favourite.
