sin (angle -- sine)

Inputs

• angle: Real angle in radians.

Outputs

• sine: Sine in the same real schema.

sin accepts Real32 and Real64 objects. The input is dereferenced and must be non-NIL.

Behavior

• A known input is evaluated at compile time.
• An unknown input produces an unknown value of the same real schema.

Example

{} () {} [
  "-- real32 --" printCompilerMessage
  0.0r32 sin printStack _:;
  1.5707964r32 sin printStack _:;
  -1.5707964r32 sin printStack _:;

  "-- real64 --" printCompilerMessage
  0.0 sin printStack _:;
  1.5707963267948966 sin printStack _:;
  -1.5707963267948966 sin printStack _:;
] "main" exportFunction

Expected Output During Compilation

-- real32 --
0.0r32
1.0r32
-1.0r32
-- real64 --
0.0
1.0
-1.0
