And Operator Example

The example assigns a value to Msg that depends on the value of variables A,

B, and C, assuming that no variable is a Null. If A = 10, B = 8, and C = 6, both

expressions evaluate True. Because both expressions are True, the And

expression is also True.

Dim A, B, C, Msg 'Declare variables.

A = 10: B = 8: C = 6 'Assign values.

If A > B And B > C Then 'Evaluate expressions.

Msg = True

Else

Msg = False

End If

ASIN (Source)

The ASIN function returns the arc sin of a number.

Syntax

x = ASIN (source)

Remarks

Source can be any valid numeric expression that has a value between -1 and 1

inclusive.

The ASIN function takes the ratio of two sides of a right triangle and returns

the corresponding angle. The ratio is the length of the side opposite to the

angle divided by the length of the hypotenuse. The result is expressed in

radians and is in the range -π/2 to π/2 radians.

To convert degrees to radians, multiply degrees by π/180. To convert radians

to degrees, multiply radians by 180/π.

ASIN is the inverse trigonometric function of Sin, which takes an angle as its

argument and returns the length ratio of the side opposite the angle to the

hypotenuse.

ASIN Function Example

The example uses ASIN to calculate π. By definition, a full circle is 2π radians.

ASIN(1) is π/2 radians (90 degrees).

Public Pi 'Declare variables.

Pi = 2 * ASin( 1 ) 'Calculate Pi.
