NUMERICAL TECHNIQUES FOR DYNAMICS SIMULATION

摘要

A method for dynamics simulation involves maintaining quantities according to a floating point binary format quantized to a first precision lower than the precision supported by the floating point format. For example, although an IEEE floating point number can represent numbers with a precision of one part in 2ˆ24, the quantities are quantized to a lower precision, such as one part in 2ˆ22. Operations are applied to sets of the quantities by quantizing the intermediate results of the operations to the lower precision than the precision supported by the floating point format.
