how to round to the nearest number unity code example

Example 1: unity round

Mathf.Round(10.2f);

Example 2: unity round float to nearest 10

//int
int sayi;
int = ((int)(((int)(sayi/10))*10));
//float
float sayi;
sayi = ((float)(((int)(sayi/10))*10));

Example 3: how to round to nearest whole number unity

// Prints 10
        Debug.Log(Mathf.Round(10.0f));

        // Prints 10
        Debug.Log(Mathf.Round(10.2f));

        // Prints 11
        Debug.Log(Mathf.Round(10.7f));
