I have a numeric entry field component bound to a float memory tag called "memoryTag05\_float". ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/e/ce028a2dd40c9f65791d3c299377e805172feb33.png) When the float memory tag has a value of -6.79168362355791e-7 the numeric display shows NaN. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/6/5656a970b7fe493bbe419e10d1762f8cb8d47fb8.png) When I click in the numeric entry field I can see the value correctly and edit it. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/1/b1639c9eb2d818ce870e141547f72226b9bff390.png) Since the formatting is set to 0,0.### I would expect the value to be displayed as zero. What's going on ? How can I get the component to display a number and not the NaN ? I changed the formatting to 0,0.############ and it still displays NaN ---

Isn't this the same question as your previous post three days ago - or have I missed something? > [@Table cell displays NaN for small number (Bug ?)](https://forum.inductiveautomation.com/t/table-cell-displays-nan-for-small-number-bug/74503): > > I have linked a dataset to a table in perspective. The table does not show scientific notation. When I enter values is removes the scientific notation. Example: The value in the dataset is 6.9592e-8. The table displays NaN. (see below). When I double click on the field to edit the value I can see the correct value: However, when I enter the value 7.8888e-8 and press enter the value is converted to 7.89 (no scientific notation) result after pressing enter: ---

No.. first question was for a dataset displayed in a data table. This is for a numeric display component directly bound to a float memory tag. But.... similar behavior perhaps. Thanks ---

I wonder if it's the e that is causing it to see this as Not a Number. Perhaps try an expression binding and manipulate your formatting in the expression. ---

Did you ever get an answer on this? How you solved it? I have the exact same issue, and I can't use formatting transform because I need it to be bidirectional to the PLC. ---

Any update on this? I am experiencing the same on 8.1.32. Have a numeric entry component value bound to a tag. Two buttons one to increment and decrement the value by .05. Works fine, but when I go from .05 to 0 it ends up as a very small decimal which is fine and expected from float arithmetic, but then the appearance becomes NaN. I know I can code it to write 0 directly if appropriate, but I just wanted it be known this is still an issue.
