Preparation: pre

Todo

presin f32 DST SRC
preex2 f32 DST SRC

  Preprocesses a float argument for use in subsequent sin/cos or ex2
  operation, respectively.

Reciprocal: rcp

Todo

rcp f32 DST SRC

  Computes 1/x.

Reciprocal square root: rsqrt

Todo

write me

rsqrt f32 DST SRC

  Computes 1/sqrt(x).

Base-2 logarithm: lg2

Todo

lg2 f32 DST SRC

  Computes log_2(x).

Sinus/cosinus: sin, cos

Todo

write me

sin f32 DST SRC
cos f32 DST SRC

  Computes sin(x) or cos(x), needs argument preprocessed by pre.sin.

Base-2 exponential: ex2

Todo

write me

ex2 f32 DST SRC

  Computes 2**x, needs argument preprocessed by pre.ex2.
