Example 1: 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 2: unity round int

//int
int sayi = 0;
sayi = ((int)(((int)(sayi / 10)) * 10));
//float
float sayi;
sayi = ((float)(((int)(sayi/10))*10));
