I've connected a slider with an edit field (moving the slider changes value in edit field and vise versa)

Problem is sometimes the slider will give a decimal wheres I need it to always round to nearest whole number.

Heres just the code within the slider callback

Image for better visualitaion plus code on bottom to copy

% Callbacks that handle component events
    methods (Access = private)
        % Value changed function: RealisationsSlider
        function RealisationsSliderValueChanged(app, event)
slider_value = app.RealisationsSlider.Value;
app.RealisationsEditField.Value = slider_value; % make slider and edit box linked
        end

any suggestions?

Much appreicated!
