I didn't really know if this stack was the right place to post but I was reading the documentation for creating an exponential random variable in numpy. But isn't there a typo. Like shouldn't it be :

$f(x; \beta) = \frac{1}{\beta} \exp(-\frac{x}{\beta})$ instead of $f(x; \frac{1}{\beta}) = \frac{1}{\beta} \exp(-\frac{x}{\beta})$?

From the source on GitHub, the function does accept $\beta$, so even if expressing the function in terms of $\frac{1}{\beta}$ (rather than $\lambda=\frac{1}{\beta}$) was typical, it is a bit misleading to present it in this way on the documentation page.
