Distance, height, thickness and astronomical length.
Try a decimal, 1e-9, 1/3, or 5 1/2.
Enter a micrometre value to calculate light-year with full internal precision before display rounding.
Auto trims unnecessary zeroes and uses scientific notation for extreme magnitudes. Use Digits to set the display precision; calculations retain full precision.
