S: the designated source value. D: the TAN value result.
The source designated by S can be given as radians or an angle; this is decided by
flag M1018.
When M1018=Off, the operation is in radians mode, where the radians (RAD) value
is equal to (angle ×π/180).
When M1018=On, the operation is in the angle mode, where the angular range is
0°≤ angle <360°.
When calculation results yield 0, M1020=On.
The TAN obtained from the source value designated by S is stored in D.
When X0=On, the TAN value of the designated binary floating point number (D1,
D0) in radians (RAD) will be stored in (D11, D10), with the content consisting of a
binary floating point number.
