Code:

using System.Collections;
using UnityEngine;

public class ClickUpgrade : MonoBehaviour {

    public Click click;
    public UnityEngine.UI.Text itemInfo;
    public float cost;
    public int count = 0;
    public float clickPower;
    public string itemName;
    private float _newCost;

    void Update()
    {
        itemInfo.text = itemName + "

Cost: " + cost + "
Power: +" + clickPower;
}

    public void PurchasedUpgrade()
    {
        if (click.BTC >= cost)
        {
            click.BTC -= cost;
            count += 1;
            click.perclick += clickPower;
            cost = Mathf.Round(cost * 2);
            _newCost = Mathf.Pow (cost, _newCost = cost);
        }
    }
}

Please check this line:

cost = Mathf.Round(cost * 2);

So if the initial value of cost is less than 0.5, then Mathf.Round makes it “0”.
