Decimal places in numeric results and text downloads

Rounding changes displayed numbers, not the calculation. Text, fractions, matrices and CSV schedules keep their own formatting. Automatic keeps up to 12 significant digits, with money shown to cents where applicable.

Step-by-step calculation

Inputs are substituted below. Each line evaluates the next operation; intermediate values are displayed to 12 significant digits while the calculation uses full precision.

Saved scenario

Save the current answer, then change an input to compare. This clears when you leave.

Formula and assumptions

Compare values within the same game and sensitivity system. This does not translate between games or account for acceleration, scoped multipliers, or operating-system scaling.

Automatic precision shows numbers to 12 significant digits. Thousands separators such as 1,000 are accepted; use a dot for decimals.

Use +, −, ×, ÷, parentheses and %. A percentage is divided by 100. This does not change the main tool.

Reset reloads the tool with its starting values and releases open files and device controls. Saved drafts stay on this device until you delete them.

A worked example

With mouse dpi = 800, in-game sensitivity = 1.5, the edpi is 1200.

Before you use the result

Compare values within the same game and sensitivity system. This does not translate between games or account for acceleration, scoped multipliers, or operating-system scaling.

Example results for mouse dpi

These examples use In-game sensitivity: 1.5. They are reference calculations, not recommended settings.
