I have a canvas where I am showing a strength points. On every exercise you do your strength gets bigger.
But sometimes I am adding to strength value like 0.3777753. After some of this operations my strength points are invsible. I want it to show only numbers with one number after comma. Like 5.6 not like 5.651234.
It looks like that:

And after some operations my value disappears

Code of the text changer looks like this;
using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class siła : MonoBehaviour
{
public static double sila=1;
Text text; // Reference to the Text component.

void Awake ()
{

	// Set up the reference.
	text = GetComponent <Text> ();

	// Reset the score.;	
}

void Update ()
{
	text.text = "Strength " + sila;
}

}
I am increasing strength with this buttons

The problem is probably because your text box is too small and to have only one decimal number you need to write this :

void Update ()
{
	text.text = "Strength " + sila.ToString("F1");
}
