Affiliate disclosure. The partner link in the masthead and in the band beside the copy on this page is a sponsored link to a partner operator, and this site may be paid if you open an account through it, at no extra cost to you. It carries rel="sponsored noopener" and opens in a new tab. The subject of this desk is the fraction a rounding leaves behind - a figure that appears on no statement - so its own interest is stated here rather than left for a footer: one link funds the site, and no operator, market, currency, price or product is named, rated or recommended anywhere on it.

About this project

This desk is one of a series, each of which takes a single gambling mechanic and explains it in full. This page sets out the concept, the method, the verification and the disclosure behind it.

the unitThe smallest amount the currency can express. In a two-decimal currency it is 0.01; the increment a stake must take is coarser and published per market.
the directionWhich way each rounding goes: down on a stake and a return, up on a duty and down on a prize. It is a rule, published, and it decides who keeps the fraction.
the volumeOne unit per event is nothing once and a figure at scale: on the samples, two thousand events of the same size retain 60.00 from the digits alone.
Direct answer

This desk explains how the smallest unit of money in a gambling account and the rounding applied to it decide what you can stake, what you are paid and what you can withdraw. It was produced from ten invented samples, verified externally after publication, and funded by a single disclosed partner link. It rates no product and recommends none.

The concept

Every gambling product is a column of numbers, and every number is rounded to a unit the operator chooses. That unit is small enough to be overlooked and consequential enough to be worth a desk: it decides what you can stake, what you are paid, what a balance really holds and what a bonus really credits. The subject was chosen because it is the arithmetic floor beneath every other desk in the series - the price, the stake, the return, the balance, the bonus, the duty and the conversion all round, and none of them owns the rounding itself.

How a page is made

  1. The sample is defined first. Each page begins with invented numbers and the arithmetic between them, so that every claim is re-derivable before a sentence is written.
  2. The direct answer is written first. Every page opens with a short answer to the question in its title, before any context.
  3. The arithmetic is shown. Every numeric claim has a worked example beside it, and no figure appears that a reader cannot check from the numbers on the page.
  4. The page is built and probed. The site is generated, then each page is read back to confirm its structure, its headings and its answer block are actually present.
  5. The site is verified externally. After publication every page, asset, internal link, canonical, structured-data block and partner link is requested and checked against the live origin.

The samples

Sample AThe unit and the increment: eight markets, seven increments, one request of 10.33.
Sample BThe stake: eight requests on a 0.10-increment market, 74.80 placed of 75.04 requested.
Sample CThe return: eight settled bets under a round-down and a round-to-nearest rule.
Sample DThe balance: eight accounts held at full precision and shown at two places.
Sample EThe bonus: eight deposits against a credit rounded down to the whole unit and capped.
Sample FThe conversion: eight amounts rounded down, 1.75% at the small end and 0.00% at the large.
Sample GThe duty and the prize: one document rounding one number up and the other down.
Sample HThe volume: two thousand events, 60.00 retained, and a control retaining nothing.

What this desk does not do

Samples I, J and R are defined on their own pages. It names no real operator, market, currency, exchange rate, price or product, and it rates nothing. It carries no ranking of any kind, no selection, no tip and no prediction. Every figure is illustrative and derives from the samples above. It explains a mechanism; it does not advise on a bet, an account or a dispute, and it does not tell a reader what to do with their money.
