| Abstract: | Considering the precision losing and error propagation of floating point arithmetic operation in space embedded software, the paper introduces the floating point database, the precision losing causation, and the error sources and error measure. Then, with several examples, the typical floating point arithmetic operations in space embedded software are analyzed, which supply a reference for space software error control. |
