Just wanted to share a small UI workaround I used in Zoho Creator.

By default, Number and Decimal fields show placeholders like:

####,####.##

Sometimes this doesn’t look clean, especially for read-only calculated fields in custom UI designs.

I was able to hide that placeholder completely by overriding the field style using a Note field + custom CSS.
code :
input.plain = "<style>input[name='Net_Fruit_Weight_kg']:read-only::placeholder { color: transparent !important; font-size: 0 !important; }</style>";

syntax:
input.Note_field_Link = "<style>input[name='Number_field_Link']:read-only::placeholder { color: transparent !important; font-size: 0 !important; }</style>";
