Title: set output precision to 16

proposed fix for #352 / #422

Tested with latest version of Bootstrap. For the snippet posted by the OP, lessphp outputs:
```
.row-fluid [class*="span"] {
display: block;
width: 100%;
min-height: 30px;
-webkit-box-sizing: border-box;
-moz-box-sizing: border-box;
box-sizing: border-box;
float: left;
margin-left: 2.127659574468085%;
*margin-left: 2.074468085106383%;
}
```
