## Julia| typemin()和typemax()函数 **(**Julia | typemin() and typemax() functions**)** ##

typemin() and typemax() are the library functions of the Julia programming language and are used to get the minimum/smallest value and maximum/largest value of a given type (data type).

typemin()和typemax()是Julia编程语言的库函数，用于获取给定类型(数据类型)的最小值/最小值和最大值/最大值。

**Syntax:**

**句法：**

typemin(T)
        typemax(T)

Here, T is the data type.

在此， T是数据类型。

**Example:**

**例：**

span style="color: #888888"># Julia example of
    # typemin() and typemax() functions
    
    println("typemin(Int8): ", typemin(Int8))
    println("typemin(Int64): ", typemin(Int64))
    println("typemin(Bool): ", typemin(Bool))
    println("typemin(Float16): ", typemin(Float16))
    println("typemin(Float32): ", typemin(Float32))
    println("typemin(Float64): ", typemin(Float64))
    
    println("typemax(Int8): ", typemax(Int8))
    println("typemax(Int64): ", typemax(Int64))
    println("typemax(Bool): ", typemax(Bool))
    println("typemax(Float16): ", typemax(Float16))
    println("typemax(Float32): ", typemax(Float32))
    println("typemax(Float64): ", typemax(Float64))

**Output**

**输出量**

typemin(Int8): -128
    typemin(Int64): -9223372036854775808
    typemin(Bool): false
    typemin(Float16): -Inf
    typemin(Float32): -Inf
    typemin(Float64): -Inf
    typemax(Int8): 127
    typemax(Int64): 9223372036854775807
    typemax(Bool): true
    typemax(Float16): Inf
    typemax(Float32): Inf
    typemax(Float64): Inf
