void copy_reg |
( |
char * |
dst, |
|
|
char * |
src |
|
) |
| |
Copy contents of src to dst, whose contents will be lost.
Perform stack function "enter".
Return exponent of register.
void plus |
( |
char * |
res, |
|
|
char * |
r1, |
|
|
char * |
r2 |
|
) |
| |
Add two registers and store result in third one.
res <– r1 + r2. Even in case of overflow, res is changed in the process.
Put argument into X register and shifts the stack.
Argument should be one of reg[A] or reg[B].
void shiftr |
( |
char * |
r, |
|
|
int |
n |
|
) |
| |
Shift mantissa n digits to the right.
Shift mantissa 1 digit to the right.
Last digit is lost, but correct rounding on second-to-last digit is assured.
