_abs8 (Absolute Value, 8 Bit)
This function returns the absolute value of a signed integer.
Stack Transformation: (a -- |a|)
Location: Near
Registers Affected: None
Example:
This example returns the absolute value of -8.
push #@lb(-d’8) ; (-d’8)
call _abs8 ; (d’8)
_add16 (Add, 16 Bit)
This function adds two 16-bit unsigned integers.
Stack Transformation: (a(2), b(2) -- a(2) + b(2))
Location: Near
Registers Affected: None
Example:
This example adds 50 to 300.
pushd #d’300 ; (d’44, 1)
pushd #d’50 ; (d’50, 0, d’44, 1)
call _add16 ; (d’94, 1)
_add16s (Add Signed, 16 Bit)
This function adds two 16-bit signed integers.
Stack Transformation: (a(2), b(2) -- a(2) + b(2))
Location: Near
Registers Affected: None
Example:
This example adds 50 to 300.
pushd #d’300 ; (d’44, 1)
pushd #d’50 ; (d’50, 0, d’44, 1)
