Retrieves the current value displayed in the spinbutton entry as a float value. Use this in combination with the PHP function round() where you need to collect the value to a specific number of decimal places.
<?php $adj = &new GtkAdjustment(0.0, 0.0, 1.0, 0.01, 0.1, 0.0); $spin = &new GtkSpinButton($adj, 0.0, 2); round($spin->get_value_as_float(), 2); ?>
