I have a big int such as 6222600820001059483 in python int type. When I send to browser use JsonResponse I found that the value was changed to 6222600820001060000.

I think this caused by the precison lose when JsonResponse send it to browser.

I think this was caused by javascript. Like What is JavaScript's highest integer value that a number can go to without losing precision? said the javascript's highest integer is small than this value.

So how to deal this between django and js?

Do you calculate anything with this value? You could keep it as string. – iklinac Apr 14 '20 at 13:49
Yeah,May be this is the right way.I read this data from pandas.So I must convert the big int field in pandas to str. – wsf1990 Apr 14 '20 at 13:55
