List of formula specification using in Templates.

Categories of functions:

Logical

Name Syntax, parameters Description Example
AND AND(Boolean1;Boolean2; ... ) Returns TRUE if all of its arguments are TRUE AND(3=3;2=2) ⇒ TRUE
OR OR(Boolean1;Boolean2; ... ) Returns TRUE if any of its arguments are TRUE OR(3=4;2=3) ⇒ FALSE
TRUE TRUE() Returns the logical value TRUE IF(TRUE();1;2) ⇒ 1
FALSE FALSE() Returns the logical value FALSE IF(FALSE();1;2) ⇒ 2
IF IF(Test;Then;Else) Specifies a logical test to perform

- inputs can be linked to data

- result can be number, text, logical value

Result is number (bold inputs linked to data X[0;1;2;3;4;5;6]):

IF(220>200;220-200;200-220) ⇒ 20

IF(120>MAX([X⇕]);120;-1) ⇒ 120

IF(MAX([X⇓2:⇓3])>[X⇓7];MAX([X⇓2:⇓3]);[X⇓7])) ⇒ 6

Result is text:

IF([Coordinate Z]>0;"Top above terrain";"Top under terrain")

IF([GWT]<[Coordinate Z];"GWT under top of the test.";"Measure error.")

IFS IFS(Test1;Then1;Test2;Then2; ... ;Else) Checks whether one or more conditions are met and returns a value that corresponds to the first TRUE condition Input [GWT] = 15

IFS([GWT]>8;10;[GWT]>6;9;[GWT]>3;8;-1) ⇒ 10

NOT NOT(Boolean) Reverses the logic of its argument
SWITCH SWITCH(Switch;Case1;Result1;Case2;Result2; ... ;[ Else ]) Evaluates an expression against a list of values and returns the result corresponding to the first matching value. If there is no match, an optional default value may be returned SWITCH(50>6;TRUE();44;FALSE();56;-111) ⇒ 44
