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. > On 16 Apr 2018, at 11:51, Serge Stinckwich <serge.stinckw...@gmail.com> wrote: > > 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.
