see attached clip. why does this happen? why it can not be just 0.9, why 0.900000000002? I want to put the channel value to the font sop, so I want it to look readable.
To use floats as text in a Font sop, it's best to format them first to the desired readable precision. Use sprintf() in VEX or format() in python to convert the float to a string before referencing in the font sop's text field.
