Increasing Decimal Places with st.number_input()

[thomsmd]

Hi, I have a quick question with regards to using st.number_input(), is it possible for the step to be increased from 0.01 to something around 4 to 5 decimal places (e.g 0.00001) using this method, if not would there be any suggestions for obtaining an input from a user that is able to reach that much accuracy?

Many thanks.

Hi @thomsmd, welcome to the Streamlit community!!

It certainly is possible! You can specify the desired precision for the step size using the step parameter, and control how the number input widget displays numbers using printf-style strings. Here’s a working example:

import streamlit as st

num = st.number_input(
    "Higher precision step",
    min_value=1.0,
    max_value=5.0,
    step=1e-6,
    format="%.5f")

st.write(num)

Does this help?

Happy Streamlit-ing!
