USUBBORROW(3G)

NAME
usubBorrow - subtract unsigned integers and generate borrow

DECLARATION

genUType usubBorrow(genUType x, genUType y, out genUType borrow);

PARAMETERS

x
    Specifies the first vector to be used in the subtraction operation.

y
    Specifies the second vector to be used in the subtraction operation.

borrow
    Specifies the variable to receive the borrow output of the difference.

DESCRIPTION

usubBorrow subtracts two 32-bit unsigned integer variables (scalars or vectors) and generates a 32-bit unsigned integer result, along with a borrow output. The result is the difference of x and y if non-negative, or 232 plus that difference otherwise. The value borrow is set to 0 if x ≥ y and to 1 otherwise.
