Description
arg
ByVal
Single
The value from which the arc sine will be computed.
Discussion
The arc sine function is the inverse of the sine function. The return value will be the angle, expressed in
radians, whose sine corresponds to the passed value. The type of the return value will be Single and
the value will range from -p/2 to p/2. If the argument is greater than 1.0 or less than 1.0, the result will
be undefined.
Example
Dim val as Single, theta as Single
val = 0.5
theta = Asin(val)
' result is approximately 0.5236
