Example
//--Converts the Cosine of -.5 to radians using .Acos method. Then pass that number into the .Cos method to return the cosine value.
var lnACos = Math.Acos(-.5)
var lcMath = 'lnACos = Math.Acos(-.5): ' + Convert.ToString(Math.Acos(-.5)) + '\n';
lcMath += 'Math.Cos(lnACos): ' + Convert.ToString(Math.Cos(lnACos)) + '\n';
Event.Form.MessageBox(lcMath);
/* Expected System Prompt Display:
lnACos = Math.Acos(-.5): 2.0943951023932
