Does MongoDB Map / Reduce save results in floats?

Question

I am using Mongoid, which is on top of the Ruby MongDB driver. Despite the fact that my Map issuer allocates parseInt(num), and Return also returns a value parseInt(num), the final results are still floats.

Is this especially important for MongoDB? Any way to make it an integer?

Answer 1

The function parseIntofficially accepts the string as a parameter. This string is parsed as if it were an integer, ignoring everything after the first non-numeric character. If you specify a floating point number, it will be converted to a string before parsing it.
