Mathematical Functions / Operations on wide Numbers

WideShift

You can use the WideShift function to shift bits in a wide number.

wide *WideShift(wide *target, long shift);

target

A pointer to the number for which the bits are to be shifted. On return, contains the shifted number.

shift

The number of bits by which the target is to be shifted to the right.

function result

A pointer to the target number.

DESCRIPTION

The shift direction is to the right (a decrease in magnitude) if the shift parameter is greater than 0, and to the left if the shift parameter is less than 0. The result of a right shift is rounded.
