Problem with "default parameter sample" in Batch experiment

[ptaillandier]

Describe the bug
In batch experiment, the proposed discret value for the parameter is wrong (with the default sample method).

To Reproduce
Steps to reproduce the behavior:

1. Create a new model with this code:

model testsample

global {
	int nb_agents <- 100;
	float distance <- 5.0;
	list<simple_agent> neighbors;
	
	init {
		create simple_agent number: nb_agents;
	}
}

grid cell width: 100 height: 100;

species simple_agent {
	reflex spatial_computation {
		using topology(cell) {
			neighbors <- neighbors + simple_agent at_distance distance;
		}
	}
}

experiment testBatchSimple type: batch until: cycle > 10 repeat: 5{
	parameter nb_agents var: nb_agents min: 100 max: 300 step: 100;
	parameter distance var: distance min: 3.0 max: 5.0 step: 1.0;
	
	reflex end_sim {
		ask simulations {
			write "End of :" + int(self) + " " +sample(self.nb_agents) + " " + sample(self.distance) + " " + sample(self.cycle);
		}
	}
}

2. launch the testBatchSimple experiment
3. Click on play
4. check the console

Expected behavior
The values for the distance variable should be: 3, 4, 5, whereas GAMA uses for values: 4, 5, 6
