IF (condition,truepart,falsepart)

This function gives one value when our specified condition is TRUE and the second value when our specified condition is FALSE.
$IF$ is the Conditional statement and it is used to perform different actions based on different conditions.
In $IF(condition,truepart,falsepart)$ , $condition$ is the logical test or expression to evaluate.
$truepart$ is any value or the string and it is displays when the specified $condition$ is TRUE.
$falsepart$ is any value or the string and it is displays when the specified $condition$ is FALSE.
For e.g, IF(A2>1000,"costly","cheap"). Here A2>1000 is the logical expression. Costly is the $truepart$ value and cheap is the $falsepart$ value.
When our mentioned amount is satisfying the $lt$ then it shows "costly". Suppose our amount is not satisfying the $lt$ it shows "cheap".
In CALCI we can give any number of $IF$ functions can be nested as $truepart$ and $falsepart$ statements to give for a complicated tests.
When $truepart$ and $falsepart$ are calculated, $IF$ returns the value returned by $truepart$ or $falsepart$ .
If any of the arguments to $IF$ are arrays, each element of the array is evaluated when the $IF$ statement is carried out.
We can use COUNTIF and SUMIF functions for more to examine our data based on a condition.

1.Number=20 IF(A2>=0,"positive","negative") = positive Number=-18 IF(A2>=0,"positive","negative") = negative

2.A1= IF(ISBLANK(A1)=TRUE,"BLANK",IF(ISTEXT(A1)=TRUE,"TEXT",IF(ISNUMBER(A1)=TRUE,"NUM","")))= BLANK

3. A1= winter IF(ISBLANK(A1)=TRUE,"BLANK",IF(ISTEXT(A1)=TRUE,"TEXT",IF(ISNUMBER(A1)=TRUE,"NUM",""))) = TEXT

4. A1=10000 IF(ISBLANK(A1)=TRUE,"BLANK",IF(ISTEXT(A1)=TRUE,"TEXT",IF(ISNUMBER(A1)=TRUE,"NUM","")))=NUM

5.C1=40,D1=90 IF(C1<D1,C1+D1,C1-D1) = 130
