Dividing On strings CS0019

Question

I want to make a progress percentage, that shows only natural numbers instead of real numbers. so I used the ToString. after that I realized that I cant use operators on strings. so what should I do?

using UnityEngine; using UnityEngine.UI; public class Progress : MonoBehaviour { #region Var public Transform Player; public Text ProgressText; #endregion #region Update //call this function per frame void Update () { ProgressText.text = Player.position.z.ToString("0") / 912.2f * 100f + "%"; } #endregion }

Divide the value before you convert it to a string?

 void Update()
 {
     float v = Player.position.z / 912.2f * 100f;
     ProgressText.text = v.ToString("0") + "%"; 
 }

Though keep in mind that the operators / and * have equal order so they are evaluated from left to right. So you actually divide by 9.122f the way you have written your numbers. Though in your case i think that's what you want.

ps: You can use "operators" on strings, but not to perform arithmetic operations. The operators have a different meaning depending on the operands. Custom classes can implement their own operators like Unity's Vector3 struct for example. Of course the string class doesn't have a multiply or divide operator as it wouldn't make any sense. What would be "Hello" * "World" or "foo" / "bar".
