PtNumericFloat widget ignoring Pt_ARG_NUMERIC_INCREMENT?

If I set Pt_ARG_NUMERIC_INCREMENT for this widget to .1 in PhAB it just
ignores it (leaves it at 1), if I set it programmatically using
PtSetResource(ABW_nameof widget, Pt_ARG_NUMERIC_INCREMENT,
&variablename, 0) the widget stops working. Am I doing something wrong
or is there a bug? Thanks.

woops, figured this one out - had the wrong data type. Never mind
