exp

Learn how to use the exp function in Notion formulas.

The

`exp()`

function allows you to raise Eulerβs Number $e$

(the base of the natural logarithm) to a higher power and get the output, where the argument is the exponent:$e^n = m$

exp(number)

β

$e$

approximately equals `2.718281828459045`

.Viewed another way, the *argument* (mathematical term) in a natural logarithm.

`exp()`

function helps you find the In other words,

`exp()`

accepts $x$

as an argument (programming term) and returns $y$

, where:$\log_e y = x$

For reference, here are the named components of a logarithm:

$\log_{base} argument = exponent$

Using

`exp()`

, we can write a Notion formula that models continuous growth of a starting population by a certain percentage each year over a certain number of years.This example is also used in the article on Eulerβs Constant (e); its use here demonstrates how

`exp(n)`

is equivalent to `e^n`

.exp

College Info Geek on Notion

// Compressed

prop("Starting Num") * exp(prop("Growth Rate") * prop("Periods"))

β

// Expanded

prop("Starting Num") *

exp(

prop("Growth Rate") *

prop("Periods")

)

As stated in the Eulerβs Constant (e) article, continuous growth of a starting number

$n$

can be expressed as:$n * e^{(rate \ of \ growth \ * \ number \ of \ time \ periods)}$

Here, we simply use the

`exp()`

function, passing `prop("Growth Rate") * prop("Periods")`

as the argument. We then multiply it by our starting number, passed via

`prop("Starting Num")`
