Syntax
Tan(number)
Argument Description number A numeric expression containing the number of radians in the angle whose tangent is to be returnedReturns
The tangent of number.
Usage
Number is specified in radians and can be either positive or negative.
The return value is single precision if the angle is an integer, currency, or single-precision value; double precision for a long, variant, or double-precision value.
To convert degrees to radians, multiply by PI/180. The value of PI is 3.14159.
Example
This example finds the height of the exterior wall of a building, given its roof pitch and the length of the building.
Sub Button_Click
Dim bldglen, wallht
Dim pitch
Dim msgtext
Const PI = 3.14159
Const conversion = PI/180
On Error Resume Next
pitch = 35
pitch = pitch * conversion
bldglen = 150
wallht = Tan(pitch) * (bldglen/2)
