Hello @ramanandmehta
Thank you very much for using our plugin. It is not a plugin issue or error but the Javascript engine implementation on browsers. Please look at the screenshot below. I evaluated the operation directly in the browser console:
The plugin includes the PREC operation to fix the accuracy issue on the browser.
PREC(X, Y) rounds the number X with Y decimals, and you should use it as the outermost operation in the equation.
You can edit your equation as follows:
PREC(0.0166666667 * 60, 2, true)
It must be read as follows: Rounds the result of the mathematical operation 0.0166666667 * 60 with two decimal places, and the last parameter tells the plugin not to include the decimal places (.00) if the mathematical operation returns an integer number.
Best regards.
