    3939There are cases where you should not try to use the Remez algorithm at all:
    40  * when the range is not finite, ''eg.'' [0,+∞]
     40 * when the '''source''' range is not finite, ''eg.'' [0,+∞]
     41 * when the '''destination''' range is not finite, ''eg.'' ''log(x)'' tends to -∞ near 0
    4142 * when the function to approximate has an infinite derivative at a point contained in or near the approximation range, ''eg.'' ''sqrt(x)'' or ''cbrt(x)'' in 0
