7.12.29 BSIN, BSINP
Function
(1) Calculates the SIN (sine) value of value (angle) designated by , and stores the sign of the operation result in the device
designated at , and the operation result in the devices designated at +1 and +2.
(2) The value designated at is a BCD value which can be between 0 and 360 degrees (in units of degrees).
(3) The sign for the operation result stored in will be "0" if the result is a positive value, and "1" if the result is a negative
value.
(4) The operation results stored in +1 and +2 are BCD values between -1.000 and 1.000.
(5) Operation results are rounded off from the fifth decimal place.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into
SD0.
Program Example
(1) The program example below calculates the SIN of 3-digit BCD data designated by X20 to X2B, and outputs a 1-digit
BCD part to the integer part from Y50 to Y53, and a 4-digit BCD fraction part from Y40 to Y4F.
Y60 is turned ON if the results of the operation are negative. (If a value has been set at X20 to X2F that is greater than
360, it will be adjusted to be in the range from 0 to 360.)
