Conversions are provided to and from suffixed size strings as used by LVM commands like lvcreate(8). These strings consist of a (possibly floating-point) number followed by an optional unit suffix: B (bytes), S (512-byte sectors), and KMGTPE for kilobytes through exabytes, respectively. Suffixes are not case-sensitive; the default unit is Megabytes. Currently, we reject negative sizes. Unlike some (but not all) LVM commands we do not interpret the upper-case version of a suffix as a power of ten.
