The ASIN and ASINP instructions are arc sine instructions for trigonometric functions. The ASIN instruction calculates the arc sine of S1 and stores the result in D1. sin-1(S1) is stored in D1. Input values between -1.0 to 1.0 for S1, and the result in D1 is a real number, measured in radians, between -Pi/2 to Pi/2. Pi is approximately 3.1415926535897 (real number).
The ASIN and ASINP instructions always pass power. When using the ASIN and ASINP instructions, an error will occur if the variables specified in operands S1 and D1 are not of the same type. Designate the same variable type in all operands S1 and D1.
Refer to the following for specifying a constant.
When operand D1 is a float variable
When 0f (zero and lower case "f") is input, the following values are interpreted as float values.
When operand D1 is a real variable
When 0r (zero and lower case "r") is input, the following values are interpreted as real values.
When calculating data in a specified array
Specify the array using Data [0] or Data [N] (N indicates an integer variable).
When operands S1 and D1 specify the entire array, an error will occur even if the specified variables are the same type.
