Abstract
Though very useful in many situations, the fixed-precision floating-point formats that are available in hardware or software in our computers may sometimes prove insufficient. There are reasonably rare cases when the binary64/decimal64 or binary128/decimal128 floating-point numbers of the IEEE 754 standard are too crude as approximations of the real numbers. This may occur for example when dealing with ill-conditioned numerical problems: internal computations with very high precision may be needed to obtain a meaningful final result.
