# TRUNC Function (DAX)

SQL Server 2008 R2

Truncates a number to an integer by removing the decimal, or fractional, part of the number.

```
TRUNC(<number>,<num_digits>)
```

Term

Definition

number

The number you want to truncate.

num_digits

A number specifying the precision of the truncation, 0 (zero) if omitted.

A number specifying the precision of the truncation; if omitted, 0 (zero)

A whole number.

TRUNC and INT are similar in that both return integers. TRUNC removes the fractional part of the number. INT rounds numbers down to the nearest integer based on the value of the fractional part of the number. INT and TRUNC are different only when using negative numbers: TRUNC(-4.3) returns -4, but INT(-4.3) returns -5 because -5 is the smaller number.

The following formula returns 3, the integer part of pi.

```=TRUNC(PI())
```

The following formula returns -8, the integer part of -8.9.

```=TRUNC(-8.9)
```
