Scientific notation is a common number notation used to express large and small numbers in the form $$x \cdot 10^y$$, where $$1 \leq |x| < 10$$ and $$y \in \mathbb Z$$.[1] In general, the formulas for finding $$x$$ and $$y$$ are

$$x = \frac{N}{10^{\left\lfloor log_{10} |N|\right\rfloor}}$$

and

$$y = \left\lfloor log_{10} |N|\right\rfloor$$.
