Mathematical Functionsfunctiondocumented

Syntax

Declare Function Cos ( ByVal angle As Double ) As Double

Parameters

Name		Description
`angle`		the angle (in radians)

Return value

Returns the cosine of the argument angle as a Double within the range of -1.0 to 1.0.

Description

The argument number is measured in radians (not degrees).

The value returned by this function is undefined for values of angle with an absolute value of 2 ^ 63 or greater.

Cos can be overloaded as operator to accept user-defined types.

Remarks

Usage



result = Cos( angle )

Differences from QB

None

Example

Const PI As Double = 3.1415926535897932

Dim a As Double

Dim r As Double

Input "Please enter an angle in degrees: ", a

r = a * PI / 180    'Convert the degrees to Radians

Print ""

Print "The cosine of a" ; a; " degree angle is"; Cos ( r ) 

Sleep

Output:

Please enter an angle in degrees: 30
The cosine of a 30 degree angle Is 0.8660254037844387
