Julia| sign()函数 (Julia | sign() function)

sign() function is a library function in Julia programming language, it returns the sign of the given value in the form of -1/+1.

sign()函数是Julia编程语言中的库函数，它以-1 / + 1的形式返回给定值的符号。

Note: If the value is 0, it returns 0.

注意：如果该值为0，则返回0。

Syntax:

句法：

    sign(val)

Parameter(s):

参数：

• val – represents a signed integer/value, whose sign (-1 or +1) to be found.

  val –表示一个有符号的整数/值，其符号(-1或+1)将被找到。

Return value:

返回值：

The return type of this method is Int64, it returns the -1 or +1 for the val.

此方法的返回类型为Int64 ，它返回val的-1或+1。

Example:

例：

    Input:
val = 0
Output:
sign(val): 0
Input:
val = -10
Output:
sign(val): -1
Input:
val = 10
sign(val): +1

Program:

程序：

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

Output

输出量

val: 0
sign(val): 0
val: 10
sign(val): 1
val: -10
sign(val): -1
val: 10.23
sign(val): 1.0
val: -10.23
sign(val): -1.0
typeof(sign(-10)): Int64
