Large numbers abbreviated as Billion might not match the user locale

[ctarda]

Describe the bug
In most countries of Western Europe, a billion equals 10^12, not 10^9.

Currently, large numbers like 1.000.000.000 (1 thousand millions) will be abbreviated as 1.0b, which for the aforementioned languages will be interpreted by users as 1.000.000.000.000 (1 million millions) instead.

To Reproduce
Steps to reproduce the behavior:

1. Generate enough sales to reach revenue of one thousand millions
2. Go to My store
3. Notice how the number is abbreviated as 1.0b

Expected behavior
Large numbers should be abbreviated having in mind that different countries might use different scales

Looks like our numeric abbreviations are turning out to be problematic. 😏 Thanks for pointing this out @ctarda
