sigfig is a Typst package for rounding numbers with significant figures and measurement uncertainty.

Documentation

`round`

round is similar to JavaScript's Number.prototype.toPrecision() (ES spec).

#assert(round(114514, 3) == "1.15e5")
#assert(round(1, 5) == "1.0000")
#assert(round(12345, 10) == "12345.00000")
#assert(round(.00000002468, 3) == "2.47e-8")

Note that what is different from the ES spec is that there will be no sign ($+$) if the exponent after e is positive.

`uround`

uround rounds a number with its uncertainty, and returns a string of both.

#assert(uround(114514, 1919) == "1.15e5+-2e3")
#assert(uround(114514.0, 1.9) == "114514+-2")

`urounds`

uround rounds a number with its uncertainty, and returns a string of both with the same exponent, if any.

You can use num in unify to display the result.
