Large numbers shows incorrectly

[Mingun]

For example, in this CSV all numbers displayed as in the last column:

"No","Actual number","JS truncation","Shows as"
1,"210727301071531090","210727301071531100","210727301071531104"
2,"210727301151031138","210727301151031140","210727301151031136"
3,"210825582544337195","210825582544337180","210825582544337184"

This seems to the JS number truncation due to that fact that JS numbers have double floating-point representation with only 52 bit of mantissa so not every 64-bit number can be exactly represented as JS number. The "JS truncation" columns shows the result from Firefox console for numbers. But this plugin also adds an own systematic error of ±4 as you can see in the last column.
