Julia| flipsign()函數(shù) (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()函數(shù)是Julia編程語言中的庫函數(shù)，它接受兩個值作為參數(shù)，并返回具有第一個值的大小和第一個值*第二個值的符號的值，即，如果返回值，則返回帶有翻轉(zhuǎn)符號的第一個值第二個值是負數(shù)。

Syntax:

句法：

flipsign(val1, val2)

Parameter(s):

參數(shù)：

• 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，即第一個值，它將用作構(gòu)建返回值的幅度。

• val2 – represents the sign value.

  val2 –表示符號值。

Return value:

返回值：

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

此方法的返回類型為Int64 ，如果val2為負，則返回帶有翻轉(zhuǎn)符號的val1 。

Example:

例：

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

Program:

程序：
