Julia| 復數 (Julia | Complex Numbers)

The syntax to represent the complex number in Julia is:

在Julia中表示復數的語法為：

Syntax:

句法：

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.

這里， A和B是值， im是全局常數，該常數綁定到表示-1的主平方根的復數i上 。

Example 1:

范例1：

# Julia program to demonstrate the example # of complex numbers and operations on itprintln(1+2im) println((1+2im)+(2+4im))# variables x = 10+23im println("x: ", x) println("typeof(x): ", typeof(x))

Output

輸出量

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

Example 2:

范例2：

# Julia program to demonstrate the example # of complex numbers and operations on itx = 1+2im y = 2.34+78.909imprintln("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

輸出量

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
