How deeply does 100 C++ Mistakes and How to Avoid Them cover static_cast?

Defines compiler compatibility checking and demonstrates numeric conversion, but defers deeper conversion mechanics.

Static_cast

As explained in 100 C++ Mistakes and How to Avoid Them

static_cast is a C++ cast expression that performs compile-time checked conversions between related or otherwise compatible types.

static_cast performs a compile-time checked conversion between compatible data types. It is the C++-style choice for ordinary conversions, such as truncating a double to an integer, while rejecting incompatible conversions. section 5.6

Replacing an unsafe C-style cast

A C-style cast can hide what conversion is intended. In the cleaned-up example, static_cast<double>(n) makes the numeric conversion explicit, while static_cast<double*>(msg) is rejected because the pointer types are incompatible. Use static_cast only when the conversion is as safe as you understand it to be. section 5.6
