Math

Design intent: Make everyday quick calculations. Skip an overpowered spreadsheet.

• Type the word "math" at the top of your note to activate math features.
• Or type "/" at the beginning of any new line, and then choose "math".
• You can title a math note with math: Your Title.
• You can type // at the beginning of a line to make it a comment. This will prevent it from being calculated.

Calculations

• Adding = to the end of any line will attempt a calculation.
• Words, punctuation, and currency symbols are stripped out.
• Valid operators include: + - * x X / ÷ ^ ** ( )
• You can also do colloquial percentage calculations: 100 + 15% = 115 or 50% of 200 = 100.
• Advanced features include: ! !! √16 ∛8 sqrt(16) log(355) log2(355) ceil(12.256) floor(12.256)
• At the moment, we do not support conversions in a calculation (e.g. 5cm to inches * 5 =).
• We support regions where the period is used as a thousands separator and the comma is used as a decimal separator (e.g. 1.000,25).
• At the moment, we do not support regions where the space is used as a thousands separator (e.g. 1 000,25).

Settings for calculations:

• Number of significant digits — 0-7
• Use a thousands separator — On | Off

Currency Conversions

Use the following format to convert currencies:

10 USD to JPY = 1,492.84 JPY

• Currency rates are updated every day. The "Update currency rates daily" toggle lives in Settings > Keywords > Math, and is also gated by Settings > Privacy ("Automatically update conversion rates daily") — both must be on for rates to refresh.
• If you use your currency symbol without a currency code, we will assume your primary currency:

$10 to JPY = 1,492.84 JPY

• If you do not put any conversion target, we will assume you want to convert your primary currency to your secondary currency:

$10 = 14.00 CAD

• At the moment, we do not support conversions in a calculation (e.g. $10 USD to CAD + 5 =).

Supported currency codes include:

Measurement Conversions

Use the following format to convert measurements:

10" to cm = 25.40 cm

At the moment, we do not support conversions in a calculation (e.g. 10 ft to m + 5 =).

Variables

You can assign values or calculations to a variable, then use the variable in other calculations.

number of guests : 9
number of guests + 1 = 10.00

• Updating the variable's value instantly updates everything that uses that variable.
• Variable names can have spaces in them.
• If you start typing 3 letters or more that match your variable, an autocomplete window will show up.
• Variable autocomplete: if there is only one option, Tab will select it for autofill. If there are multiple, Tab will choose the first option and pressing a number key will choose the corresponding one.
• You can assign the results of conversions to a variable. However, it will store only the resulting number and not the unit / currency.

table width : 58 cm to in = 22 13/16"
table width = 22.81

• When using a variable that is the result of a conversion, you have to manually add the unit / currency if you want to use the variable in a subsequent conversion.

cost in CAD : 50 USD to CAD
cost in CAD CAD to USD = 50.00 USD
