CenteredInterval
CenteredInterval[x, dx] for real numbers x and dx gives a centered interval that contains the real interval from x-dx to x+dx.
CenteredInterval[x + I*y, dx + I*dy] gives a centered interval that contains the complex rectangle.
CenteredInterval[c] for an approximate number c gives a centered interval that contains all values within the error bounds of c.
