Description
Returns the arcsine of expr in radians. In other words, if expr represents the sine of some angle, then asin(expr) returns the angle. The returned angle will be in the range of -π/2 to +π/2 radians (which corresponds to -90 to +90 degrees). asin always returns a double-precision result.
