valid limbs, representing the new absolute value for < span class = "parameter" > x< / span > , and the sign of < span class = "parameter" > x< / span >
is taken from the sign of < span class = "parameter" > s< / span > .
This function never reallocates < span class = "parameter" > x< / span > , so the limb pointer remains valid.
