Data is being updated but not being saved.

[WOLFGANGHASH]

I use both Node.js with JavaScript and PHP with MySQL commands. I am experiencing a very interesting issue. The variable type is set as float. Data is easily updated in both systems. Decimal numbers are displayed. After values of 10,000 and above, sometimes the data is not updated, but sometimes it is. There are no errors, everything is working smoothly. Why might this issue have occurred? How can it be resolved?
