Learn how to use the exp function in Notion formulas.

The exp() function allows you to raise Euler’s 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) number.exp()

\(e\) 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 \(x\) as an argument (programming term) and returns \(y\), where:

\(\log_e y = x\)

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

\(\log_{base} argument = exponent\)

exp(2) /* Output: 7.389056098931 */ 5.exp() /* Output: 148.413159102577 */ e ^ 5 /* Output: 148.413159102577 */ exp(ln(5)) /* Output: 5 */ 5.ln().exp() /* 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.

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

As stated in the Euler’s 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").
