## 15.2 Literals: decimal and scientific notation

In programming languages such as Stan, numbers may be represented in standard decimal (base 10) notation. For example, 2.39 or -1567846.276452. Remember there is no point in writing more than 16 significant digits as they cannot be represented. A number may be coded in Stan using scientific notation, which consists of a signed decimal representation of a base and a signed integer decimal exponent. For example, 36.29e-3 represents the number $$36.29 \times 10^{-3}$$, which is the same number as is represented by 0.3629.
