I think Float randomFrom: -4.1 to: 2.5 or Float randomBetween: -4.1 and: 2.5 would be the most descriptive and compliant to your signature ;-) An interval does not necessarily contain Floats. Going to the class side of Float makes sense because you create a new instance.

Hi Pharoers,
some random musings about Random numbers :-)
In the context of the CORMAS project: http://cormas.cirad.fr/indexeng.htm I would like to propose an API for manipulating random numbers to users who are not developers but modelers of complex systems.
In CORMAS, people need to generate a lot of random numbers for simulation for exemple. For example, you can do:
Cormas randomFloatFrom: -4.1 to: 2.5
âAt the moment, there is no Pharo API to generate with a one-liner a random float number between two values for example.
You can do this for integers: 10 atRandom to generate an integer between 1 to 10.
There is atRandom defined on Interval, so can you say : (2.3 to: 4.5) atRandom but it will not generate a random float numbers between 2.3 and 4.5
but numbers like: 2.3, 3.3 or 4.3. because Interval are considered as a Collection.
âAny comments about that ? How we can enhance the situation ?â Any interest to introduce a method to produce random float numbers in an interval in Pharo ?
