====== Simatic S7 SCL commands with examples ======
=== trigonometric / math functions ===
[[de:s7:scl_commands#cos|COS (cosinus)]], 
[[de:s7:scl_commands#exp|EXP (exponential)]], 
[[de:s7:scl_commands#sin|SIN (sinus)]], 
[[de:s7:scl_commands#tan|TAN (tangent)]]

===== EXP =====
The function returns the value of the "EXP" (exponent from the base e (e = 2.718282)) math function.

<color green>Result</color> := EXP(<color blue>Value</color>);


<color green>Result</color>: the return value of the function \\
<color blue>Value</color>: function input \\

A yellow underline in the code indicates that the result of the function is not completely accurate for [[de:s7:tia_datatypes#real|REAL]] and [[de:s7:tia_datatypes#int|INT]] types. For [[de:s7:tia_datatypes#lreal|LREAL]] type, precision is complete.

===== COS =====
The function returns the value of the "COS" (cosinus) trigonometric function.

<color green>Result</color> := COS(<color blue>Value</color>);


<color green>Result</color>: the return value of the function \\
<color blue>Value</color>: function input \\

A yellow underline in the code indicates that the result of the function is not completely accurate for [[de:s7:tia_datatypes#real|REAL]] and [[de:s7:tia_datatypes#int|INT]] types. For [[de:s7:tia_datatypes#lreal|LREAL]] type, precision is complete.

===== SIN =====
The function returns the value of the "SIN" (sinus) trigonometric function.

<color green>Result</color> := SIN(<color blue>Value</color>);


<color green>Result</color>: the return value of the function \\
<color blue>Value</color>: function input \\

===== TAN =====
The function returns the value of the "TAN" (tangent) trigonometric function.

<color green>Result</color> := TAN(<color blue>Value</color>);


<color green>Result</color>: the return value of the function \\
<color blue>Value</color>: function input \\
