# Rounding Floating Point Number To two Decimal Places in C and C++

How to round off a floatig point value to two places. For example, 5.567 should become 5.57 and 5.534 should become 5.53

First Method:- Using Float precision

 `#include ` `using` `namespace` `std; ` `int` `main() ` `{ ` `    ``float` `var = 37.66666; ` ` `  `    ``// Directly print the number with .2f precision ` `    ``printf``(``"%.2f"``, var);  ` `    ``return` `0; ` `} `

```Output:
37.67
```

Second Method : Using integer typecast If we are in Function then how return two decimal point value

 `#include ` `using` `namespace` `std; ` `float` `round(``float` `var) ` `{ ` `    ``// 37.66666 * 100 =3766.66 ` `    ``// 3766.66 + .5 =3767.16    for rounding off value ` `    ``// then type cast to int so value is 3767 ` `    ``// then divided by 100 so the value converted into 37.67 ` `    ``float` `value = (``int``)(var * 100 + .5); ` `    ``return` `(``float``)value / 100; ` `} ` ` `  `int` `main() ` `{ ` `    ``float` `var = 37.66666; ` `    ``cout << round(var); ` `    ``return` `0; ` `} `

```Output:
37.67
```

Third Method : using sprintf() and sscanf()

 `#include ` `using` `namespace` `std; ` `float` `round(``float` `var) ` `{ ` `    ``// we use array of chars to store number ` `    ``// as a string. ` `    ``char` `str;  ` ` `  `    ``// Print in string the value of var  ` `    ``// with two decimal point ` `    ``sprintf``(str, ``"%.2f"``, var); ` ` `  `    ``// scan string value in var  ` `    ``sscanf``(str, ``"%f"``, &var);  ` ` `  `    ``return` `var;  ` `} ` ` `  `int` `main() ` `{ ` `    ``float` `var = 37.66666; ` `    ``cout << round(var); ` `    ``return` `0; ` `} `

```Output:
37.67
```
