Problem

Currently there are several helpers in the template language (see scripting/bson_template_evaluator.cpp) for creating various random or sequential integers.

Geo data relies upon the usage of floating point numbers. Current issues

• No helper to generate floating point numbers
• Current integer helpers will throw a stack trace if a float is passed, eg

  tests.push( { name: "testing",
                tags: ['insert','sanity','daily','weekly','monthly'],
                pre: function( collection ) { collection.drop(); },
                ops: [
                    { op:  "insert", 
                      doc: { x: { {"#RAND_INT":[-73.965095, -73.961673]  } } }
                ] } );
  

  Will result in

Solution

Provide template helpers for float dataypes
