SUMMARY

The two functions TRUNC() and INT() are similar, but return slightly different results for negative numbers. The INT() function rounds a number down to the previous integer. The TRUNC() function simply truncates the decimal portion of a number.

A comparison is described in the chart below.

       Number      INT()     TRUNC()
       ------      -----     -------
        1.5          1          1
        1            1          1
       -1.5         -2         -1
       -1           -1         -1
