operator>= is the operator to determine if the left-hand instance is greater or equal the right-hand instance.
The following code uses operator>= to determine that one plus two is greater or equal equal to three:
#include <iostream> int main() { if (1 + 2 >= 3) std::cout << "One plus two is greater or equal than three.\n"; }
operator>= is encapsulated by the functor std::greater_equal.
- Reversing the order of the pair of symbols in the operators !=, >= and <= (by writing them as =!, => and =< respectively) is normally a syntax error [1]

Chapter 2.4, Common Programming Error 2.2. page 32: 'Reversing the order of the pair of symbols in the operators !=, >= and < (by writing them as =!, => and =< respectively) is normally a syntax error. In some cases, writing != as =! will not be a syntax error, but almost certainly will be a logic error that has an effect at execution time.'
