Result formats

Select a math region that already shows an answer. Then pick how that number is written: 24500, 2.45 × 10⁴, or 24.5 × 10³. Format only changes the display. The stored value stays the same.

Change the format

1. Select one or more math regions that already show an answer. That means ones whose expression ends in a trailing =. Several regions selected together all take the new setting.
2. Open the Math Format tab.
3. In Results, open Format and choose one of the five entries below. The sheet re-evaluates and the chips redraw.

A new math region starts at Auto, and copying a region brings its format along.

Choosing between the five

Format	Reach for it when	Example at Decimals 2
Auto	You want a compact form and do not care much. Whole numbers stay whole. Magnitudes past Exp thresh. (default 6, meaning 10⁶ or 10⁻⁶) switch to a scientific-style display on their own.	24500 → 24500, but 2400000 → 2.4 × 10⁶
Decimal	A column of answers should line up at a fixed number of places. Fixed-point, using Decimals (0–15, default 2). Trailing 0s decides whether those places are padded.	8.4375 → 8.44
Scientific	Magnitude matters more than the digits: moduli, tolerances, anything spanning several orders. One digit before the point, then a power of ten, with Decimals applying to the significand.	24500 → 2.45 × 10⁴
Engineering	You read the exponent as a unit prefix. Powers move in steps of three, so 10³ reads as k, 10⁶ as M, 10⁻³ as m, 10⁻⁶ as µ. Handy alongside a preferred unit.	24500 → 24.5 × 10³
Fraction	The number is really an imperial dimension or a simple ratio. Calculeaf writes a rational approximation of the magnitude, and the unit still appears on the chip.	0.375 → 3/8

What Format does not touch

Format never changes the stored quantity, the worksheet unit system, or any downstream math. R * 2 still uses the same R whether you display R as 24 kN or 2.40 × 10¹ kN.

Next, decimal places for how many digits to show, and what Zero tol. and Exp thresh. do.
