# 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.
