1-8IntroductionintegerAn integer is a positive or negative number that has a valuebetween –2 63 and (263 – 1). Although the valid range is usuallymuch smaller, all integers have 64 bits of precision and do notcontain decimal points.You can specify an integer as a mathematical equation that uses anasterisk (*) to multiply, a plus sign (+) to add, a minus sign (–) tosubtract, a slash (/) to divide, and parentheses [( )] to specify orderof operations. If you do not use parentheses, all operations arecompleted 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 binaryYou can attach special multipliers to the end of any number toallow for easy translation to reasonable disk sizes. Table 1-1 liststhe letters and their multiplicative values:You cannot use decimal points. To specify 1.5 GB, for example, youmust use (3G/2).Note: All suffixes are case-insensitive. That is, you can useupper or lower-case characters. For example you canspecify 10 M or 10 m.Table 1-1 Letters and Multiplicative ValuesLetter ActionK (kilobytes) multiplies by 1024M (megabytes) multiplies by 1024*1024G (gigabytes) multiplies by 1024*1024*1024T (terabytes) multiplies by 1024*1024*1024*1024
