Does MongoDB support floating point types?

Question

I am migrating a mysql database to mongodb. But i have read in MongoDb data types and then there is no reference to floating point types like, float, double, decimal.

Answer 1

MongoDB does support storing doubles, but not all drivers provide an interface to them for some reason.

From http://www.mongodb.org/display/DOCS/Data+Types+and+Conventions -

Mongo uses special data types in addition to the basic JSON types of string, integer, boolean, double, null, array, and object.
