All the numerical options, if not specified otherwise, accept in input |
|
a string representing a number, which may contain one of the |
|
International System number postfixes, for example 'K', 'M', 'G'. |
|
If 'i' is appended after the postfix, powers of 2 are used instead of |
|
powers of 10. The 'B' postfix multiplies the value for 8, and can be |
|
appended after another postfix or used alone. This allows using for |
|
example 'KB', 'MiB', 'G' and 'B' as postfix. |
