There are only two kinds of programming languages: those people always bitch about and those nobody uses. Bjarne Stroustrup
A complex number is a combination of real and imaginary numbers. A+Bi is a complex number where A is the real number and B is the imaginary number.
A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit,
3 - real number
4 - imaginary number
Add:8.0+6.0i + 4.0+5.0i = 12.0+11.0i Subtract:8.0+6.0i - 4.0+5.0i = 4.0+1.0i Multiply:8.0+6.0i * 4.0+5.0i = 2.0+64.0i
