Default settings
Radix 10 (decimal).
Functional description
This directive specifies the radix that will be used by default. The Cross-Assembler provides three
coding formats for numbers.
•
Extended C language format
•
Intel format
•
Matsushita format
The format is selected with the notation directive. Refer to the description of the notation directive.
The default is extended C language format.
The radix directive specifies the default radix for numbers in these coding formats by the expression in
the operand. Select one from radix 2 (binary), radix 8 (octal), radix 10 (decimal), and radix 16
(hexadecimal).
NOTE:
In extended C language format, the default radix cannot be specified by the radix
directive. The default is fixed as radix 10 (decimal), and it cannot be changed to
another radix
Operand coding rules
The expression coded in the operand must result in the attribute abs (absolute). Refer to section 8.7.4,
"Expression Attributes", regarding attributes of expressions.
The calculated result of the expression coded in the operand must be either 2, 8, 10, or 16. The radix of
the expression in the operand is always 10 (decimal), regardless of the current default radix. If the
expression results in a number that does not specify a radix, the assembler will generate an error and
ignore this directive.
Usage example
Below is an example use of the radix directive.
radix
16
radix
BINARY
