Frontend - wijmo with pure js

Backend - asp.net core 3.1 with GemBox.Spreadsheet package.

Guys, how can we solve an issue with rounds?

From DB we, for example, receive the number 0.00360000 I need to receive as a result in the cell value 0.0036. Currently, I setup number format on the backend and usually receive correct data on the frontend (e.g. 0.0036), but when I enter something either from the formula bar or directly in the cell, for example, number 0.003601, I need to dynamically change cell format and receive number 0.003601, but actually, now it will be rounded to 0.0036. To DB will be saved correct number (e.g. 0.003601)

Need a help
