Artifact fa129b5c42a47db0c05c3694dc61c732ad6c4ef4:

• File operator/subtract-rgb-rgb.crimp — part of check-in [b0d870cef2] at 2011-12-15 01:25:30 on branch infinite-plane — Reorganized the binary ops, added result type to the generated file names, and added a few combinations always generating float, for operators like atan2 and hypot.

  Updated all users of the binop_*.c files. Reworked pow to use the binop machinery.

  Created special binary ops template for fpcomplex operations which are not element-wise (multiply, div), and updated the actual operators to use this. (user: andreask size: 480) [more...]
