Does anyone know if there is a easy way to change a negitive int value into a
positive int value.

int a = -105 > change this to 105.

With other words is there a command to change to neg sign into pos sign ?

If you mean to change it after a value has already been assigned to 'a':

    Negative or Positive --> Positive
        a = Math.Abs(a)

    Reverse the sign
        a = -(a)
    or
        a = a * -1

a = a<0 ? -a : a; // if a is negative >>or<< positive

Thanks Bob , Stephany and Till,

Math.abs(<value>) does the trick.
Also thanks for the other tips. a = -(a) is a handy one to remember.
