# &O

The &O prefix denotes that a integer value is expressed in an Octal base 8 format.

==Syntax== a& = &O12345671234

• The base eight numbering system only uses octal digit values of 0 to 7.
• Leading zero values can be omitted as they add nothing to the return value.
• Decimal values returned can be any signed INTEGER, LONG integer, or _INTEGER64 value so use those type of variables when converting directly as shown above. The program "overflow" error limits are listed as:
* INTEGER: 6 octal digits or a decimal value range from -32,768 to 32,767
* LONG: 11 octal digits or a decimal value range from -2,147,483,648 to 2,147,483,647
* _INTEGER64: 22 octal digits or decimal values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
• LONG Octal values can be expressed by appending & after the number. Example: &O100000& = 32768

Example: The maximum octal values of decimal value -1 in each numerical type are:

c&& = -1: d& = -1: e% = -1: f%% = -1 oc\$ = OCT\$(f%%) PRINT "Max octal _BYTE = "; oc\$; " with"; LEN(oc\$); "digits ="; VAL("&O" + oc\$) oc\$ = OCT\$(e%) PRINT "Max octal INTEGER = "; oc\$; " with"; LEN(oc\$); "digits ="; VAL("&O" + oc\$) oc\$ = OCT\$(d&) PRINT "Max octal LONG = "; oc\$; " with"; LEN(oc\$); "digits ="; VAL("&O" + oc\$) oc\$ = OCT\$(c&&) PRINT "Max octal _INTEGER64 = "; oc\$; " with"; LEN(oc\$); "digits ="; VAL("&O" + oc\$)

Max octal _BYTE = 377 with 3 digits = 255 Max octal INTEGER = 177777 with 6 digits = 65535 Max octal LONG = 37777777777 with 11 digits = 4294967295 Max octal _INTEGER64 = 1777777777777777777777 with 22 digits =-1
