Use of Trig functions in VB 2010 1

[Ken01]

I have a program which uses the Arcsin and Arccos features of the language.

I have found that if the value to be converted into an angle is 1 or greater then the calculated value
returns as "Nan".
If the value is less than 1 then the angle calculates correctly.

Is this a known problem and are there any solutions.

Hi,

The domain of y = arcsin(x) is

and its range is

I had to look this up since it's been a mighty long time since I used these trig functions in my slipstick.

So naturally, values of x greater than 1 or less than -1 will return an error.
