Julia | Complex Numbers

The syntax to represent the complex number in Julia is:

Syntax:

    A+Bim

Here, A and B are the values, and im is the global constant which is bound to the complex number i representing the principal square root of -1.

Example 1:

# Julia program to demonstrate the example 
# of complex numbers and operations on it

println(1+2im)
println((1+2im)+(2+4im))

# variables
x = 10+23im
println("x: ", x)
println("typeof(x): ", typeof(x))

Output

1 + 2im
3 + 6im
x: 10 + 23im
typeof(x): Complex{Int64}

Various operations on Complex Numbers

Example 2:

# Julia program to demonstrate the example 
# of complex numbers and operations on it

x = 1+2im
y = 2.34+78.909im

println("x: ", x)
println("y: ", y)

# operations
add = x+y
sub = x-y
mul = x*y
div = x/y
exp = x^2

# printing
println("add: ", add)
println("sub: ", sub)
println("mul: ", mul)
println("div: ", div)
println("exp: ", exp)

Output

x: 1 + 2im
y: 2.34 + 78.909im
add: 3.34 + 80.909im
sub: -1.3399999999999999 - 76.909im
mul: -155.478 + 83.589im
div: 0.02569885734584168 - 0.011910741155137315im
exp: -3 + 4im
