Introduction
integer
An integer is a positive or negative number that has a value
between –2
63
and (2
63
– 1). Although the valid range is usually
much smaller, all integers have 64 bits of precision and do not
contain decimal points.
You can specify an integer as a mathematical equation that uses an
asterisk (*) to multiply, a plus sign (+) to add, a minus sign (–) to
subtract, a slash (/) to divide, and parentheses [( )] to specify order
of operations. If you do not use parentheses, all operations are
completed left to right. No spaces are allowed in the expression.
Numbers in an equation that:
■ Begin and end with no suffix are decimal
■ Begin with 0x or end with h are hexadecimal
■ End with o indicate octal
■ End with z indicate binary
You can attach special multipliers to the end of any number to
allow for easy translation to reasonable disk sizes. Table 1-1 lists
the letters and their multiplicative values:
You cannot use decimal points. To specify 1.5 GB, for example, you
must use (3G/2).
Note: All suffixes are case-insensitive. That is, you can use
upper or lower-case characters. For example you can
specify 10 M or 10 m.

Letter Action
K (kilobytes) multiplies by 1024
M (megabytes) multiplies by 1024*1024
G (gigabytes) multiplies by 1024*1024*1024
T (terabytes) multiplies by 1024*1024*1024*1024
