Different Integer

In C++, you have a huge amount of varieties of numbers. When you add unsigned in front of a type like int (except : bool, char) then the type will no longer support negative numbers.

• Bool  0 or 1
• Char  0 to 9
• Short  - 2^16 to 2^16
• Int (32 bits) -2^32 to 2^32
• Long or long long -2^63 to 2^63
• Unsigned long long 0 to 2^64

You also have complex numbers in C++ if you include the following line : #include <complex>
When you have included that line, you can :

• initialise a complex table like this : complex<double> mycomplex(10.0,0.01);
• print the real part with real()
• print the imaginary part with imag()
• print the phase angle of a complex number with arg()
• print the complex projection with proj()
• print the complex conjugate with conj()
• print the norm of a complex  number with norm()
• print absolute value of a complex number with abs()
