Precision and calculation record

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.

Saved scenario

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

Formula and assumptions

Only a linear equation is supported. A zero coefficient can mean no intercept or an entire axis, which is reported explicitly.

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

A worked example

Example inputs: coefficient a in ax + by = c = 2, coefficient b = 3, constant c = 12. X-intercept = 6.

Before you use the result

Only a linear equation is supported. A zero coefficient can mean no intercept or an entire axis, which is reported explicitly.

Example results for coefficient a in ax + by = c

These examples use Coefficient B: 3; Constant C: 12. They are reference calculations, not recommended settings.
