DOWN

Rounding mode to round towards zero. Never increments the digit prior to a discarded fraction (i.e., truncates). Note that this rounding mode never increases the magnitude of the calculated value.

Example:

<table class="striped"> <caption>Rounding mode DOWN Examples</caption> <thead> <tr style="vertical-align:top"><th scope="col">Input Number</th> <th scope="col">Input rounded to one digit<br></br> with `DOWN` rounding </th></tr></thead> * <tbody style="text-align:right"> <tr><th scope="row">5.5</th> <td>5</td> </tr> * <tr><th scope="row">2.5</th> <td>2</td> </tr> * <tr><th scope="row">1.6</th> <td>1</td> </tr> * <tr><th scope="row">1.1</th> <td>1</td> </tr> * <tr><th scope="row">1.0</th> <td>1</td> </tr> * <tr><th scope="row">-1.0</th> <td>-1</td> </tr> * <tr><th scope="row">-1.1</th> <td>-1</td> </tr> * <tr><th scope="row">-1.6</th> <td>-1</td> </tr> * <tr><th scope="row">-2.5</th> <td>-2</td> </tr> * <tr><th scope="row">-5.5</th> <td>-5</td> </tr></tbody> * </table> *
