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

���At 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.

���Any comments about that ?
How we can enhance the situation ?���

Any interest to introduce a method to produce random float numbers in an interval in Pharo ?

���Thank you���
