Engineers are not always right… just take standard Harddrive measurements; the standard is that it takes (based off the metric-system) 1000 to get 1 ( 1000kB = 1MB, 1000MB = 1GB… etc.); now for those that know the basics for the binary-numbers and how data is stored know that this is totally wrong… 8bit = 1 Byte and then it goes to 1024 to get 1 (1024 byte = 1kB, 1024kB = 1MB… etc.)
this is why harddrives will alway have smaller capacity than what is written on the label (and in the description on the store’s page).
There is nothing wrong with how CCP have chosen to display numbers, which is the general way that most countries have it, comma = thousand separator and point = decimal separator. I can understand the frustration, but if you apply some common sense to the numbers, EVE always round up to the nearest 2-decimal’s place, so when the game write 3,400 billion why would you then assume it meant “3.4”?, it goes against all accounting logic. The specific contract may be a scam but no harm done, atleast not for the OP, as he mentioned he did not have enough to fulfill the contract.
