(1) The following program performs a TAN operation on the angle data set by the 4 BCD digits from X20 to X2F, and stores
the results as 64-bit floating decimal point type real numbers at D0 to D3.
[Ladder Mode]
[List Mode]
[Operations involved when X20 to X2F designate a value of 135]
: SIN value of which the SIN
-1
(inverse sine) value is obtained or head number of the devices where the SIN value is stored (real number)
: Head number of the devices where the operation result will be stored (real number)
