About number_input for very small number

[Sunix_Liu]

Hi team, I need to input some very small number like: 0.0000045, but when I’m trying to use st.number_input, it seems it doesn’t support this, it could only show number like 0.00.
temp = st.number_input(label=‘test’,min_value=0.000000,step=0.000001,max_value=0.0005,value=0.0000045)

Is there any way to resolve this?

Hi @Sunix_Liu -

Adding the format parameter worked for me:

import streamlit as st

temp = st.number_input(
    label="test",
    min_value=0.000000,
    step=0.000001,
    max_value=0.0005,
    value=0.0000045,
    format="%f",
)

st.number_input - Streamlit Docs

Best,
Randy
