# Overview

You can put the relevant expression into a hidden value that represents = the integer form of the value.

### Roun= d a number down to the nearest integer

If you want to round a number down you can use the int() function to cut= off the decimal point (i.e. 2.2 -> 2; 2.7 -> 2)

`int(#form/value) `

### Round a number up to the nearest integer

Use the following calculation to always round a number up (i.e. 2.2 ->= ; 3; 2.7 -> 3)

```If( int(#form/value) < #form/value, int(#form/value) + 1, int(#form=
/value))```

This compares whether the decimal form of the lowest integer is smaller tha= n the current value, and if so, rounds up, and otherwise truncates the valu= e.

### Round a number up from .5, otherwise down<= /span>

As of CommCare 2.19, the "round" function is available. Simply write round(= #form/value). Read more  her= e.
You can also use the int() function in combination with multiplying the inp= ut by 2, adding 1, and then dividing by 2 (i.e. 2.2 -> 2; 2.7 -> 3)
int ( ( #form/value*2 +1 ) div 2 )
To round to a different number of decimal places, appropriately adjust the = constant '2' in the preceding calculation. The constant should be twice the= inverse of the desired precision. For example, for a precision of 0.1, con= stant =3D 1 / precision * 2 =3D 1 / 0.1 * 2 =3D 20. Consequently use i= nt ( ( #form/value*20 +1 ) div 20 ).

### Round= a number to a certain decimal place

You can use the same principles to round to the nearest .1, .01, .001, etc.= with the following formula:
Round to nearest decimal:   round(#form/value*10) div 10
To round to two decimals change the 10's in the formula above to 100. To th= ree decimals change them to 1000, etc.
