where "" is the polar argument of the vector corresponding to the function ATAN2(y,x) (or in double precision DATAN2(y,x)) available in for example the programming language FORTRAN.
Unlike SSE2, AltiVec supports a special RGB "pixel" data type, but it does not operate on 64-bit double precision floats, and there is no way to move data directly between scalar and vector registers.
However, float in Python, Ruby, PHP, and OCaml and single in versions of Octave prior to 3.2 refer to double-precision numbers.
