[Koha] Koha upgrade from 3.16 to 16.11

[Nicolas Legrand]

Hey Jonathan, Hey Hugo,

we also have trouble in 16.11 with tax calculation :

mysql> select unitprice_tax_excluded, unitprice_tax_included from
aqorders join aqinvoices on aqinvoices.invoiceid = aqorders.invoiceid
where aqinvoices.invoiceid = 2674 limit 10;
+------------------------+------------------------+
| unitprice_tax_excluded | unitprice_tax_included |
+------------------------+------------------------+
|              80.400000 |              80.400000 |
|              32.760000 |              32.760000 |
|             110.700000 |             110.700000 |

|              18.590000 |              18.590000 |

We had a lot of errors while upgrading we unfortunately didn't pay attention to:

Use of uninitialized value in multiplication (*) at
./installer/data/mysql/updatedatabase.pl line 13614.
[A LOT MORE OF THE SAME THING]
Use of uninitialized value in multiplication (*) at
./installer/data/mysql/updatedatabase.pl line 13619.
Upgrade to 16.06.00.043 done (Bug 13323 - Change the tax rate on receiving)


I'm going to investigate this, if someone as good ideas I'm eager to
hear from them :).
