Complex Numbers
Initializing Complex Numbers
There are two complex types in Go+. The complex64 and the complex128.
Initializing complex numbers is really easy. You can use the constructor or the initialization syntax as well.
c1 := complex(10, 11) // constructor init
c2 := 10 + 11i // complex number init syntax
println c1, c2
Parts of a Complex Number
There are two parts of a complex number. The real and imaginary part. We use functions to get those.
cc := complex(23, 31)
realPart := real(cc) // gets real part
imagPart := imag(cc) // gets imaginary part
println realPart, imagPart
Operations on a Complex Number
A complex variable can do any operation like addition, subtraction, multiplication, and division.
Let’s see an example to perform mathematical operations on the complex numbers.
c11 := complex(10, 11) // constructor init
c22 := 10 + 11i // complex number init syntax
ccc := complex(2, 3)
cc2 := 4 + 5i // complex initializer syntax a + ib
cc3 := c11 + c22 // addition just like other variables
println "Add: ", cc3 // prints "Add: (6+8i)"
re := real(cc3) // get real part
im := imag(cc3) // get imaginary part
println ccc, cc2, re, im // prints 6 8
