description Methods and apparatus for double precision division/inversion vector computations on Single Instruction Multiple Data (SIMD) computing platforms are described. In one embodiment, an input argument is represented by an exponent portion and a fraction portion. These portions are scaled, inverted, and multiplied to generate an inverse version of the input argument. In an embodiment, the inversion of the exponent portion may be done by changing the sign of the exponent. Other embodiments are also described.
