julia fit 函数

## Julia| abs()函数 **(**Julia | abs() function**)** ##

**abs() function** is a library function in Julia programming language, it is used to get the absolute value of the given signed integer.

**abs()函数**是Julia编程语言中的库函数，用于获取给定有符号整数的绝对值。

**Note:** There an overflow occurs when the function is applied to the minimum value of a data type.

**注意：**将函数应用于数据类型的最小值时，会发生溢出。

**Syntax:**

**句法：**

abs(val)

**Parameter(s):**

**参数：**

*  val – represents a signed integer/value, whose absolute value to be found.
    
    val –表示一个有符号的整数/值，其绝对值将被找到。

**Return value:**

**返回值：**

The return type of this method is Int64, it returns the absolute value of val.

此方法的返回类型为Int64 ，它返回val的绝对值。

**Example:**

**例：**

Input:
        val = 0
        Output:
        abs(val): 0
    
        Input:
        val = -10
        Output:
        abs(val): 10
    
        Input:
        val = 10
        abs(val): 10

**Program:**

**程序：**

# abs() Function with Example in Julia
    
    val = 0
    println("val: ", val)
    println("abs(val): ", abs(val))
    
    val = 10
    println("val: ", val)
    println("abs(val): ", abs(val))
    
    val = -10
    println("val: ", val)
    println("abs(val): ", abs(val))
    
    val = 10.23
    println("val: ", val)
    println("abs(val): ", abs(val))
    
    val = -10.23
    println("val: ", val)
    println("abs(val): ", abs(val))
    
    # special case
    println("typemin(Int64): ", typemin(Int64))
    println("abs(typemin(Int64)): ", abs(typemin(Int64)))
    
    # printing the return type of abs()
    println("typeof(abs(-10)): ", typeof(abs(-10)))

**Output**

**输出量**

val: 0
    abs(val): 0
    val: 10
    abs(val): 10
    val: -10
    abs(val): 10
    val: 10.23
    abs(val): 10.23
    val: -10.23
    abs(val): 10.23
    typemin(Int64): -9223372036854775808
    abs(typemin(Int64)): -9223372036854775808
    typeof(abs(-10)): Int64
