unclear on dcc.Input type argument effect

I assumed that dcc.Input(..., type='number') would return the contents as an int or float. My request:

• if this is false and dcc.Input are always of type str, could this be made more clear in the docs?

• if this should be the case, could someone take a look at what’s going on?

• in either case, could the docs be more clear about the effect of the type argument? At present it simply says “The type of control to render.” I’m starting to suspect it only affects a minor appearance of the input box.

Thanks!

@Madhu94 @jwhendy - Thanks for reporting! Sorry about this - the build on 0.15.0 was bad. I’ve updated this on v0.15.2, so give this a try:

pip install dash-core-components==0.15.2

import dash
import dash_core_components as dcc
import dash_html_components as html

app = dash.Dash()

app.layout = html.Div([
    dcc.Input(id='input', type='number'),
    html.Div(id='output')
])


@app.callback(
    dash.dependencies.Output('output', 'children'),
    [dash.dependencies.Input('input', 'value')])
def update_output(value):
    print type(value)
    return value


if __name__ == '__main__':
    app.run_server(debug=True)

Rockin! I just replicated @Madhu94 's example from #124 and it works like a charm now. Thanks for the quick fix!
