Initiation Discounts round down instead of up

What steps will reproduce the problem?
1. Create a magician caracter in career mode that has 12+ Karma.
2. Add an Initiation Grade and apply the Initiation Ordeal discount.
3. Check spent Karma.

What is the expected output? What do you see instead?

An Initiation Ordeal reduces the Karma cost to initiate by 10%.

10% of 13 Karma (for the first grade of initiation) is 1.3, in SR5 you round up 
unless told otherwise by a specific rule (page 48 SR5, A note on rounding) 
meaning the Initiation with the Initiation Ordeal should cost 11 Karma instead 
of 13 Karma.

The Initiation costs 12 Karma instead instead of 11.

What version of the product are you using? On what operating system?
Chummer 5.139
Windows 7, 64 bit

Please provide any additional information below.
This probably also applies to any other initiation discount (Schooling, Group 
Initiation) as well as any combination of discounts.
