NOTE:
Adding Decimal Numbers is commutative:
a + b = b + a
whatever finite decimal fractions a and b.
Example: 61.23 = 61.23 5.41 5.41 without gathering.
Assembly is finished decimal fractions of their association, namely: (a + b) + c = a + (b + c), irrespective of the finite decimal fractions A and B.
Exemple:
(5,41 +61,23)+3,1=5,41+(61,23+3,1)
