wide *WideMultiply(long multiplicand, long multiplier, 
                     wide *target);

multiplicand

The number to be multiplied by the multiplier.

multiplier

The number by which the multiplicand is to be multiplied.

target

A pointer to the location where the product of the two numbers is to be stored.

function result

A pointer to the target value, which holds the result.

DESCRIPTION

The operation has a bias of 0 bits. The bias of the result is the sum of the biases of the inputs.
