now function to get time in your time zone. You can prefix this functions with time zone location (or use
in with time zone suffix) to get current time for specified location. Results are always in sync with global time, so, at any point of time you will get the right time.
It's also possible to convert specific time or date from one time zone into another. Or calculate difference between time in different time zones:
PST time New York time Time in Madrid 2:30 pm HKT in Berlin
App activation required for the time zone support
You can use sign and word operators. Several expressions might be stacked together. Notice, expressions will be multiplied if used in parentheses one after another.
8 times 9 1 meter 20 cm = 120 cm 6 (3) = 18

Besides decimal numeral system, it is possible to use numbers in binary, octal or hexadecimal form using appropriate prefix:
0x. You can use
scientific to format results in scientific notation.

You can use ISO 4217 codes for currency (like USD, RUB, CAD etc). You can also use common currency names and signs, like
$ for the US dollars,
roubles for Russian roubles, or
€ for Euro. Numi updates currency rates several times a day using open exchange rates service. Numi also supports a huge list of cryptocurrencies with hourly rates updates.

In addition to general percentage operations like adding or subtracting percent of value (
$10 - 40%), you also can use additional operations:
|Percentage value||20% of $10|
|Adding percentage||5% on $30|
|Substracting percentage||6% off 40 EUR|
|Percentage value of one value relative to another||$50 as a % of $100|
|Percentage addition of one value relative to another||$70 as a % on $20|
|Percentage subtraction of one value relative to another||$20 as a % off $70|
|Value by percent part||5% of what is 6 EUR|
|Value by percent addition||5% on what is 6 EUR|
|Value by percent substraction||5% off what is 6 EUR|
Scales used for shorter form of writing big numbers. Please note that one-letter scales are case-sensitive, since
m used for meters, and
K used for Kelvins. Supported scales: thousands (
thousand), millions (
million), billions (

You can declare variables and reuse them using the
= operator. Please note some characters and keywords cannot be used as a variable. For example,
K might be used as a temperature unit in Kelvin. Variable names should not contain whitespaces or special characters, and should not start with number:
v = $20 v2 = 5% v times 7 - v2 v += $10
By default trigonometrical functions uses parameters in radians.

Numi supports several CSS units: pixels (px), points (pt), em. Em is set to 16 px by default, but you can assign different value to it. Conversion from screen units to other length units performed using pixel per inch value (ppi). By default
ppi is set to 96 pixels, which mean in every inch there're 96 pixels. You can set custom value for
12 pt in px em = 20px 1.2 em in px 1 inch in px = 96 px ppi = 326 1 cm in px = 128,35 px

You can calculate sum of all lines above (until empty line) using
total ) operator.
Line 1: $10 Line 2: $15 Result: sum
You can calculate an average of all lines above (until empty line) using
avg ) operator.
Line 1: $10 Line 2: $20 Result: average
SI-based units support all SI prefixes, both short and long form. Note that SI prefixes are case-sensitive. For example, use
MB for megabytes, not mB:
1 mm 2 picometers 3 GB
To make time calculations more straightforward, 1 year is equal to 365 days, and 1 month equal to 1/12 of the year. In cases where results give non-integer value, round functions might be used to make an integer. Supported units: Second, minute, hour, day, week, month, year. Use
fromunix function to convert timestamp into dates.
round(1 month in days) fromunix(1446587186)
Supported units: kelvin, celsius, fahrenheit
Supported units: meter, mil, points, lines, inch, hand, foot, yard, rod, chain, furlong, mile, cable, nautical mile, league. Note, since
in used as a conversion operator, you cannot use it for inches.
Supported units: hectare, are, acre and all "squared" length units. Use
sq prefix for this case.
20 sq cm 30 square inches 11 sqm
Supported units: Pint, quart, gallon, tea spoon, table spoon, cup. It is possible to use all length units with
20 cu cm 30 cubic inches 11 cbm
Supported units: gram, tonne, carat, centner, pound, stone, ounce.
Supported units: radians, degree. You can use both as text form of unit (radians, degrees) as sign. For example, 45 °
Bytes multiplies contain 1000 bytes. If you need 1024 multiplier, use kibibytes. Please note lowercase
b is used for bits, and uppercase
B for bytes.
Use hash symbol at the beginning of the line to make a header. If you want to comment part of the line, use double quotes. To comment all line, use double slash. Use colon to make a label (label will not be evaluated).
# This is header $275 for the "Model 227" // This is comment Price: $11 + $34.45

Numi does not modify imported files until you explicitly export them. All exported files have .numi extension. You can open .numi files with any text editor since Numi uses plain text and UTF-8 encoding to store files.
To use workflow make sure Numi is running. Prefix your calculations with
n, for example,
n (20% of 45)/12 or
n $20 in Euro. Please note, time zones functionality is not available via integration.
