5.6 ARC COSINE Instruction (ACOS)
[Outline]
The ACOS instruction uses the Source as the input and stores the arc cosine (unit = degrees) of the
input in the Dest. This instruction can be used in a real number operation.
[Format]
Symbol : ACOS
Full Name : Arc Cosine
Category : FUNCTION

[Parameter]
Parameter Name Setting
Source
(Input) · Any real number type register
· Any real number type register with subscript
· Constant
Dest
(Output) · Any real number type register (except for # and C register)
· Any real number type register with subscript (except for # and C register)
[Program Example]
The arc cosine of the input value (0.5) [ACOS (0.5) = X = 60.0 degrees] is calculated.
Notes: ARC COSINE Instruction cannot be used for integer type and double-length integer type
data.
