8 MATH FUNCTIONS

VTB manages a wide SET of mathematical functions.

8.1 SIN

Return the sinus of an angle in a FLOAT value.

Hardware All

Syntax

Sin (angle) as float

The argument angle can be a FLOAT value or any numeric expression which represents the angle in radians.

Example:

Used variables:

angle float

Cosec float

angle = 1.3 ‘ Define the angle in radians.

cosec = 1 / Sin (angle) ‘ Calculate the cosecant.

8.2 COS

Return the cosinus of an angle in a FLOAT value.

Hardware All

Syntax

Cos (angle) as float

The argument angle can be a FLOAT value or any numeric expression which represents the angle in radians.

Example:

Used variables:

angle float

sec float

angle = 1.3 ‘ Define the angle in radians.

sec = 1 / Cos (angle) ‘ Calculate the secant.

8.3 SQR

Return the square root of a number.

Hardware All

Syntax

Sqr (number) as float

The argument number can be a FLOAT value or any numeric expression greater or equal than zero.

Example

Used variables:

vsqr float

vsqr = sqr (4) ‘ return the value 2

8.4 TAN

Return the tangent of an angle in a FLOAT value.

Hardware All

Syntax

Tan (angle) as float

The argument angle can be a FLOAT value or any numeric expression which represents the angle in radiant.
