[Operations involved when X20 to X33 designates value of 0.4753]
: Number of the device where data of which the COS
-1
(inverse cosine) value is obtained is stored (BCD 4 digits)
: Head number of the devices where the operation result will be stored (BCD 4 digits)
Function
(1) Returns the COS
-1
(inverse cosine) value of the value designated by , and stores operation results at device
designated by .
(2) A sign for the operation data is set at .
If the operation data is a positive value, this is set at "0", and if it is a negative value, it is set at "1".
(3) The part before the decimal point and fraction part are stored at +1 and +2 respectively, as BCD values.
(Settings can be between 0 and 1.0000.)
(4) The operation results stored at will be a BCD value in the range of between 0 and 180° (degree units).
(5) Calculation results are a value from which the decimal fraction part has been rounded.
