trunc

Type

function

Summary

Returns the integer part of a number.

Syntax

the trunc of <number>

trunc(<number>)

Description

Use the trunc function to round a number down.

The trunc function is different from round in that truncation completely ignores the fractional part of the number. For example, round(4.9) returns 5, but trunc(4.9) returns 4. This means that the trunc function does not always return the integer closest to the number.
