Detailed Description

template<class T>
class OverflowSafeInt< T >

Overflow safe template for integers, i.e.

integers that will never overflow when you multiply the maximum value with 2, or add 2, or subtract something from the minimum value, etc.

Parameters

T	the type these integers are stored with.

Member Function Documentation

◆ operator*=()

template<class T >

constexpr OverflowSafeInt& OverflowSafeInt< T >::operator*= ( const int factor )

inlineconstexpr

Safe implementation of multiplication.

Parameters

factor the factor to multiply this with.

Note: when the multiplication would yield more than T_MAX (or less than T_MIN), it will be T_MAX (respectively T_MIN).

Definition at line 113 of file overflowsafe_type.hpp.

◆ operator+=()

template<class T >

constexpr OverflowSafeInt& OverflowSafeInt< T >::operator+= ( const OverflowSafeInt< T > & other )

inlineconstexpr

Safe implementation of addition.

Parameters

other the amount to add

Note: when the addition would yield more than T_MAX, it will be T_MAX.

Definition at line 53 of file overflowsafe_type.hpp.

◆ operator-=()

template<class T >

constexpr OverflowSafeInt& OverflowSafeInt< T >::operator-= ( const OverflowSafeInt< T > & other )

inlineconstexpr

Safe implementation of subtraction.

Parameters

other the amount to subtract

Note: when the subtraction would yield less than T_MIN, it will be T_MIN.
