Strictly superior statement weird behavior with "supposed" integer variables

Hello,
I encounter a strange behaviour from strictly superior statement for if condition.
Under a while loop I’ve got the following code

	textmsg("*********FullBin: ",FullBin)
	textmsg("*********FullBin_Cnt: ",FullBin_Cnt[Cycle])
	textmsg("*********(FullBin_Cnt[Cycle]>FullBin): ",(FullBin_Cnt[Cycle]>FullBin))
	if (FullBin_Cnt[Cycle]>FullBin):
		textmsg("########Current Best Cycle: ",Cycle)
		FullBin=FullBin_Cnt[Cycle]
		textmsg("########FullBin: ",FullBin)
		Pdt_X=Pdt_X_Method
		Pdt_Y=Pdt_Y_Method
		Pdt_Z=Pdt_Z_Method
		Nb_Max=NbPdtMax_Method
		Solution=Sol_Method
		Drop_Pdt_Nb_X=Pdt_Nb_X_Method
		Drop_Pdt_Nb_Y=Pdt_Nb_Y_Method
		Drop_Pdt_Nb_Z=Pdt_Nb_Z_Method
		Off_X=Offset_X_Meth
		Off_Y=Offset_Y_Meth
		Drop_Side_Meth=Drop_Side_Method
		Best_Cycle=Cycle
	end

FullBin_Cnt[Cycle] is an array which contain a multiplication result for each cycle.
FullBin is initialized to 0.
If FullBin_Cnt[Cycle] is strictly superior to FullBin then FullBin take the value of FullBin_Cnt for the current cycle.
When the while loop is finished:
FullBin_Cnt=[0,26,30,16,18,30,0,0]
FullBin=30
Best_Cycle=5 instead of 2.

To understand what was wrong I choose to subtract FullBin_Cnt[Cycle(=5)] and FullBin, when both were supposed to be 30.
The result is 7.10543e - 15.

The variable are supposed to be integer, how come that the difference is not 0?
