Equivalent function for Math.signum(double) for int or long in Java

Is there an equivalent function for Math.signum(double) or Math.signum(float) in Java for other primitive numbers like int or long. I don't want to write code like

  int sign = (int) Math.signum((double) intValue);

when there is a better alternative.

Solution

  • You can use it this way:

    Integer.signum(int i) and Long.signum(long l)
