_div8 (Divide, 8 Bit)

This function divides two integers to produce an integer result. The result of

dividing by zero is zero and a software error is logged.

Stack Transformation: (a, b -- a/b)

Location: Near

Registers Affected: R0, R1, R2

Example:

This example divides 9 by 2.

pushs #d’2 ; (d’2)

push #d’8 ; (d’9, d’2)

call _div8 ; (d’4)

_div8s (Divide Signed, 8 Bit)

This function divides two signed integers to produce a signed integer result. The

result of dividing by zero is zero and a software error is logged.

Stack Transformation: (a, b -- a/b)

Location: Near

Registers Affected: R0, R1, R2

Example:

This example divides 8 by 2.

pushs #d’2 ; (d’2)

push #d’8 ; (d’8, d’2)

call _div8s ; (d’4)
