## Julia| 文字零和一 **(**Julia | Literal zero and one**)** ##

In Julia, if we need to find the literal 0 and 1 corresponding to a specific data type we need to use zero() and one() functions. Julia provides these two library functions for this purpose.

在Julia中，如果需要找到与特定数据类型相对应的文字0和1，则需要使用zero()和one()函数。 为此，Julia提供了这两个库函数。

zero() and one() functions accept a type/value and returns the literal 0 and 1 corresponding to a specific data type, type of the given value/variable.

zero()和one()函数接受类型/值，并返回与特定数据类型(给定值/变量的类型)相对应的文字0和1。

**Syntax:**

**句法：**

zero(x)
        one(x)

Here, x is the data type or value or variable.

在此， x是数据类型或值或变量。

**Example 1: Finding literal 0 and 1 of given data type**

**示例1：查找给定数据类型的文字0和1**

# Julia example of
    # zero() and one() functions
    
    println("zero(Int64): ", zero(Int64))
    println("zero(Float32): ", zero(Float32))
    println("zero(Float64): ", zero(Float64))
    println("zero(Bool): ", zero(Bool))
    
    println("one(Int64): ", one(Int64))
    println("one(Float32): ", one(Float32))
    println("one(Float64): ", one(Float64))
    println("one(Bool): ", one(Bool))

**Output**

**输出量**

zero(Int64): 0
    zero(Float32): 0.0
    zero(Float64): 0.0
    zero(Bool): false
    one(Int64): 1
    one(Float32): 1.0
    one(Float64): 1.0
    one(Bool): true

**Example 2: Finding literal 0 and 1 of given value type**

**示例2：查找给定值类型的文字0和1**

# Julia example of
    # zero() and one() functions
    
    println("zero(10): ", zero(10))
    println("zero(10.23): ", zero(10.23))
    println("zero(true): ", zero(true))
    println("zero(-10): ", zero(-10))
    println("zero(-10.23): ", zero(-10.23))
    
    println("one(10): ", one(10))
    println("one(10.23): ", one(10.23))
    println("one(true): ", one(true))
    println("one(-10): ", one(-10))
    println("one(-10.23): ", one(-10.23))

**Output**

**输出量**

zero(10): 0
    zero(10.23): 0.0
    zero(true): false
    zero(-10): 0
    zero(-10.23): 0.0
    one(10): 1
    one(10.23): 1.0
    one(true): true
    one(-10): 1
    one(-10.23): 1.0

**Example 3: Finding literal 0 and 1 of given variable type**

**示例3：查找给定变量类型的文字0和1**

# Julia example of
    # zero() and one() functions
    
    a = 10
    b = 10.23
    c = true 
    d = -10
    e = -10.23
    
    println("zero(a): ", zero(a))
    println("zero(b): ", zero(b))
    println("zero(c): ", zero(c))
    println("zero(d): ", zero(d))
    println("zero(e): ", zero(e))
    
    println("one(a): ", one(a))
    println("one(b): ", one(b))
    println("one(c): ", one(c))
    println("one(d): ", one(d))
    println("one(e): ", one(e))

**Output**

**输出量**

zero(a): 0
    zero(b): 0.0
    zero(c): false
    zero(d): 0
    zero(e): 0.0
    one(a): 1
    one(b): 1.0
    one(c): true
    one(d): 1
    one(e): 1.0
