Description

The ASIN() function returns the angle size of sine value. The sine value is represented by the numeric expression <expN>. The numeric expression must fall between -1.0 and +1.0 inclusive. The angle size is returned as a numeric in radians. The SET DECIMALS command determines the number of decimals displayed in the returned angle size.

Example

set decimals to 4
?asin(0.7071)
    0.7854
set decimal to 2
?rtod(asin(sin(dtor(30))))
     30.00
