Function Trigonometric functions
Operations of SIN (sine), COS (cosine), TAN (tangent), ASIN (arcsine),
ACOS (arccosine) and ATAN (arctangent) are executed.

Trigonometric function
(SIN, COS, TAN, ASIN, ACOS, ATAN)
[Explanation]
(1) The operation of the specified trigonometric function is performed.
(2) The operation result is a 32-bit integer (BIN value) including four decimal places.
(3) When the argument of the trigonometric function has no decimal point, the
operation result is similarly a BIN value including four decimal places.
[Program Example]
#2010 : L = SIN [60.] ; #2010 : L = 8660
#2016 : L = SIN [600000] ; #2016 : L = 8660
#2020 : L = COS [45.] ; #2020 : L = 7071
#2026 : L = COS [450000] ; #2026 : L = 7071
#2030 : L = TAN [30.] ; #2030 : L = 5773
#2036 : L = TAN [300000] ; #2036 : L = 5773
#2040 : L = ASIN [0.8660] ; #2040 : L = 599970
#2046 : L = ASIN [8660] ; #2046 : L = 599970
#2050 : L = ACOS [0.7071] ; #2050 : L = 450005
#2056 : L = ACOS [7071] ; #2056 : L = 450005
#2060 : L = ATAN [1.] ; #2060 : L = 450000
#2066 : L = ATAN [10000] ; #2066 : L = 450000
