I believe you are looking for Math.abs(). Using this function:
我相信您正在寻找Math.abs()。使用此功能：
5 = Math.abs(5) = Math.abs(-5)
回答by bouteillebleu
The function's in the Math libraryand is called abs()(short for "absolute value").
该函数位于 Math 库中并被调用abs()（“绝对值”的缩写）。
回答by Lajos Arpad
Math.abs() is the function you are looking for.
Math.abs() 是您正在寻找的函数。
