See e.g. the examples above. Both carry and borrow translate to "Übertrag" in German – the 'borrow' in
subtraction is a specialty of the USA. See the subtle methodic differences in subtracting shown in detail in

, the general rules for setting and clearing carry and overflow are as
min
Effect on carry
Sets c if there is a carry out of the
most significant bit, else clears c.
Sets c in a subtraction m – s if
in 1COMP / 2COMP the binary
subtraction causes a borrow
into the most significant bit,
in UNSIGN m is smaller than s,
in SIGNMT m is smaller than s
and both have the same sign.
Else clears c.
None.
None.
Sets c if the remainder is ≠ 0, else
clears c.
Sets c if x = - 1, or in UNSIGN if
x = wsize or in the other modes if
x = wsize - 1. Else clears c.
Sets c for x < 0 (and for 0
clears c.
Sets c for x ≠ 0, else clears c.
None.
