    5.8 x 2.19

    = (5.00 + 0.80) x (2.00 + 0.19)

    = 5.00*2.00 + 5.00*0.19 + 0.80*2.00 + 0.80*0.19

    = 10.00 + 0.95 + 1.60 + 8/10 * 19/100

    = 10.00 + 0.95 + 1.60 + (8 * (10+9)) / 1000

    = 10.00 + 0.95 + 1.60 + (80+72) / 1000

    = 10.00 + 0.95 + 1.60 + 152/1000

    = 10.000 + 0.950 + 1.600 + 0.152

    = 11.600 + 0.950 + 0.152

    = 12.550 + 0.152

    = 12.702

    It actually is a reasonable value.
