Decimal Places and Trailing Zeros

Next to Format on the Math Format tab: Decimals (0–15, default 2) and a checkbox Trailing 0s. The Thresholds group has Zero tol. and Exp thresh. All four apply to the selected math regions.

Math Format Results and Thresholds groups showing Decimals, Trailing 0s, Zero tol., and Exp thresh. — Results and Thresholds. Decimals and Trailing 0s sit with Format; the two thresholds have their own group.

Decimals and trailing zeros

Decimals is how many digits after the point Decimal, Scientific, and Engineering use. Auto also respects it when Trailing 0s is on.

With Trailing 0s on, results pad to that width — including whole numbers in Auto (12 becomes 12.00 if Decimals is 2).
Off, trailing fractional zeros are trimmed (12.00 displays as 12, or 12.5 if that is the value).

The tooltip on the checkbox: pad results to Decimals (including whole numbers in Auto) when on; trim trailing fractional zeros when off.

A math result with Decimals set to 4 and Trailing 0s turned on. — Decimals 4 and Trailing 0s on. The chip shows four places even when the value is exact.

Zero tolerance

Zero tol. (0–20, default 15) is the number of decimal places used to treat a magnitude as zero. A residual smaller than that threshold prints as 0.

Raise it if a near-zero residual should still print as a tiny number.
Lower it to snap numerical noise to 0 (for example after a solve).

Exponent threshold

Exp thresh. (1–20, default 6) is when Auto switches to a scientific-style display. A value of 6 means magnitudes at or beyond 10⁶ (or 10⁻⁶) may change form. Decimal, Scientific, Engineering, and Fraction ignore this control — they already chose a form.

Choose Auto, Decimal, Scientific, Engineering, or Fraction first — see result formats. To pin a unit on the chip, use preferred unit.
