exp
Learn how to use the exp function in Notion formulas.
The exp() function allows you to raise Euler’s Number
ee
(the base of the natural logarithm) to a higher power and get the output, where the argument is the exponent:
en=me^n = m
1
exp(number)
ee
approximately equals 2.718281828459045.
Good to know: exp(n) is equivalent to e^n. See e (Constant) for more.
Viewed another way, the exp() function helps you find the argument (mathematical term) in a natural logarithm.
In other words, exp() accepts
xx
as an argument (programming term) and returns
yy
, where:
logey=x\log_e y = x
For reference, here are the named components of a logarithm:
logbaseargument=exponent\log_{base} argument = exponent

exp(ln(5)) // Output: 5

ln(exp(5)) // Output 5

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 Euler’s Constant (e); its use here demonstrates how exp(n) is equivalent to e^n.

// Compressed
prop("Starting Num") * exp(prop("Growth Rate") * prop("Periods"))
// Expanded
prop("Starting Num") *
exp(
prop("Growth Rate") *
prop("Periods")
)
As stated in the Euler’s Constant (e) article, continuous growth of a starting number
nn
can be expressed as:
ne(rate of growth  number of time periods)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").
