Mixpanel allows you to force Properties into another data type by using the "Data Type" option in the overflow menu for property filters and breakdowns.
Typecasting is helpful when one of your properties is a number but is sent to Mixpanel as a string and you want to see histogram data for that property. Or if one of your properties is a unix timestamp and got sent as a number, and you want it to be treated as a date Property instead.
How do I see the exact numeric values when applying a breakdown to a number data type in Insights?
Insights will automatically bucket high-cardinality segments of number data types into ranges.
You can either customize the ranges by clicking "Customize Range".
Or alternatively, if you'd like to see the exact numeric values you can typecast the Number property to a String to remove the range bucketing.
