SafeInt Functions

The SafeInt library provides several functions that you can use without creating an instance of the SafeInt Class. If you want to protect a single mathematical operation from integer overflow, you can use these functions. If you want to protect multiple mathematical operations, you should create SafeInt objects. It is more efficient to create SafeInt objects than to use these functions multiple times.

These functions enable you to compare or perform mathematical operations on two different types of parameters without having to convert them to the same type first.

Each of these functions has two template types: T and U. Each of these types can be a Boolean, character, or integral type. Integral types can be signed or unsigned and any size from 8 bits to 64 bits.




Adds two numbers and protects against overflow.


Casts one type of parameter to another type.


Divides two numbers and protects against dividing by zero.

SafeEquals , SafeGreaterThan, SafeGreaterThanEquals, SafeLessThan, SafeLessThanEquals, SafeNotEquals

Compares two numbers. These functions enable you to compare two different types of numbers without changing their types.


Performs the modulus operation on two numbers.


Multiplies two numbers together and protects against overflow.


Subtracts two numbers and protects against overflow.
