Calculator

There is no calculator command to open. Type a question in root search and the answer appears in a card above the results.

Press ↵ to copy the answer. ⌘↵ copies the raw unformatted value, and ⌘⇧↵ copies the whole question = answer line.

Nothing appears unless what you typed actually parses, so an app name or a snippet keyword never produces a stray calculator row.

Arithmetic

1024 * 8
(3 + 4) ^ 2
17 mod 5
sqrt(144) + ln(e)

Operators are + - * / ^ %, with parentheses. Words work too: plus, minus, times, x, divided by, mod, power. pi and e are constants, and a trailing deg converts degrees to radians.

Functions available: sqrt, cbrt, abs, round, floor, ceil, ln, log10, log2, exp, sin, cos, tan, cot, sec, csc, asin, acos, atan, sinh, cosh, tanh, asinh, acosh, atanh.

Half-typed parentheses are closed for you, so the answer keeps updating while you type.

Percentages

15% of 240
20% off 85
8% on 50
15% tip on 62

of takes the percentage, off subtracts it, and on and tip on add it to the total. A bare 52% on its own just divides by a hundred.

Unit conversion

128 gb to mb
10ft in m
72f to c
5 miles in km

Split on either in or to. Covered categories are length, mass, temperature, data size, area, volume and speed, with the usual aliases, so ft, feet and foot all work.

Three special targets go beyond plain units: px at N ppi, to timespan, and in workdays.

Currency

100 usd to eur
€50 in gbp
1.5k eur to jpy

Currency codes and symbols both work, in either order. Rates come from a public exchange-rate service and are cached, refreshed when they are more than twelve hours old.

This is the one part of the calculator that uses the network. Everything else is computed locally.

Date and time

time in 4 hours
days until 31 Mar
August 5 + 5
5pm ldn in sf
diff paris

Timezone phrases understand around forty city aliases mapped to real timezones, so ldn, sf and paris resolve without you naming a zone. Cities outside that list simply do not match, and no row appears.

In snippets

{calculator expression="..."} evaluates an expression inside a snippet. Currency is the exception there: the snippet path is given no rate table, so a currency conversion is left unexpanded. See the placeholder reference.
