Julia| flipsign()函数 (Julia | flipsign() function)

flipsign() function is a library function in Julia programming language, it accepts two values as parameters and returns a value with the magnitude of first value and sign of the first value*second value i.e. it returns the first value with its flipped sign if the second value is negative.

flipsign()函数是Julia编程语言中的库函数，它接受两个值作为参数，并返回具有第一个值的大小和第一个值*第二个值的符号的值，即，如果返回值，则返回带有翻转符号的第一个值第二个值是负数。

Syntax:

句法：

    flipsign(val1, val2)

Parameter(s):

参数：

• val1 – represents the magnitude value i.e. first value that will be used as a magnitude to construct the return value.

  val1 –表示幅度值，即第一个值，它将用作构建返回值的幅度。

• val2 – represents the sign value.

  val2 –表示符号值。

Return value:

返回值：

The return type of this method is Int64, it returns val1 with its flipped sign if val2 is negative.

此方法的返回类型为Int64 ，如果val2为负，则返回带有翻转符号的val1 。

Example:

例：

    Input:
val1 = 0
val2 = 0
Output:
flipsign(val1, val2): 0
Input:
val1 = -123
val2 = 10
Output:
flipsign(val1, val2): -123
Input:
val1 = 123
val2 = -1
Output:
flipsign(val1, val2): -123
Input:
val1 = -123
val2 = -1
Output:
flipsign(val1, val2): 123

Program:

程序：

# flipsign() Function with Example in Julia
val1 = 0
val2 = 0
println("val1: ", val1)
println("val2: ", val2)
println("flipsign(val1, val2): ", flipsign(val1, val2))
val1 = -10
val2 = 0
println("val1: ", val1)
println("val2: ", val2)
println("flipsign(val1, val2): ", flipsign(val1, val2))
val1 = 10
val2 = -10
println("val1: ", val1)
println("val2: ", val2)
println("flipsign(val1, val2): ", flipsign(val1, val2))
val1 = -10.20
val2 = 1
println("val1: ", val1)
println("val2: ", val2)
println("flipsign(val1, val2): ", flipsign(val1, val2))
val1 = -10.23
val2 = -10
println("val1: ", val1)
println("val2: ", val2)
println("flipsign(val1, val2): ", flipsign(val1, val2))
# printing the return type of flipsign()
println("typeof(flipsign(123, -10)): ", typeof(flipsign(123, -10)))
