cassandra: wrong computation of the number of experiments to run

[montanier]

For certain parameters of config files the computation of the number of experiments seems wrong. For example in the config file of the attached zip file, when asking a variation of alpha from 0.1 to 1.0 by steps of 0.5, cassandra computes 3 experiments (it should be 2). When clicking on "generate" the following exception is thrown:

app exception thrown: Laboratory::computeExperiments - number of experiments: 5 does not match with computed number: 4 for attribute: alpha of element: controller

Probably due to to a floating point error, the computation does not always return the same result.
