Floating point significant digits
WebSubtracting nearby numbers in floating-point arithmetic does not always cause catastrophic cancellation, or even any error—by the Sterbenz lemma, if the numbers are close enough the floating-point difference is exact. But cancellation may amplifyerrors in the inputs that arose from rounding in other floating-point arithmetic.
