Adding formula column

Can use column names in equation
Can use explicit numberical values/ strings as needed
Table below lists supported formula & associated syntax
Nested formula (formula equation referring to another formula column) are not supported

Name	Syntax	Sample	Output
ABS	`ABS(value)`	`ABS(Column)`	Absolute value of the input parameter
ADD	`ADD(value1,[value2,...])`	`ADD(Column1, Column1)`	Sum of input parameters
AVG	`AVG(value1,[value2,...])`	`AVG(Column1, Column1)`	Average of input parameters
CEILING	`CEILING(value)`	`CEILING(Column)`	Rounded next largest integer value of input parameter
EXP	`EXP(value)`	`EXP(Column)`	Exponential value of input parameter (`e^x`)
FLOOR	`FLOOR(value)`	`FLOOR(Column)`	Rounded largest integer less than or equal to input parameter
INT	`INT(value)`	`INT(Column)`	Integer value of input parameter
LOG	`LOG([base], value)`	`LOG(10, Column)`	Logarithm of input parameter to the base (default = e) specified
MAX	`MAX(value1,[value2,...])`	`MAX(Column1, Column2, Column3)`	Maximum value amongst input parameters
MIN	`MIN(value1,[value2,...])`	`MIN(Column1, Column2, Column3)`	Minimum value amongst input parameters
MOD	`MOD(value1, value2)`	`MOD(Column, 2)`	Remainder after integer division of input parameters
POWER	`POWER(base, exponent)`	`POWER(Column, 3)`	`base` to the `exponent` power, as in `base^exponent`
ROUND	`ROUND(value)`	`ROUND(Column)`	Nearest integer to the input parameter
SQRT	`SQRT(value)`	`SQRT(Column)`	Square root of the input parameter

Operator	Sample	Description
`+`	`column1 + column2 + 2`	Addition of numeric values
`-`	`column1 - column2`	Subtraction of numeric values
`*`	`column1 * column2`	Multiplication of numeric values
`/`	`column1 / column2`	Division of numeric values

To change order of arithmetic operation, use round bracket parantheses ()
Example: (column1 + (column2 * column3) / (3 - column4 ))

Name	Syntax	Sample	Output
CONCAT	`CONCAT(str1, [str2,...])`	`CONCAT(fName, ' ', lName)`	Concatenated string of input parameters
LEFT	`LEFT(str1, [str2,...])`	`LEFT(Column, 3)`	`n` characters from the beginning of input parameter
LEN	`LEN(str)`	`LEN(Title)`	Input parameter character length
LOWER	`LOWER(str)`	`LOWER(Title)`	Lower case converted string of input parameter
MID	`SUBTR(str, position, [count])`	`MID(Column, 3, 2)`	Alias for `SUBSTR`
REPEAT	`REPEAT(str, count)`	`REPEAT(Column, 2)`	Specified copies of the input parameter string concatenated together
REPLACE	`REPLACE(str, srchStr, rplcStr)`	`REPLACE(Column, 'int', 'num')`	String, after replacing all occurrences of `srchStr` with `rplcStr`
RIGHT	`RIGHT(str, count)`	`RIGHT(Column, 3)`	`n` characters from the end of input parameter
SEARCH	`SEARCH(str, srchStr)`	`SEARCH(Column, 'str')`	Index of `srchStr` specified if found, 0 otherwise
SUBSTR	`SUBTR(str, position, [count])`	`SUBSTR(Column, 3, 2)`	Substring of length 'count' of input string, from the postition specified
TRIM	`TRIM(str)`	`TRIM(Title)`	Remove trailing and leading whitespaces from input parameter
UPPER	`UPPER(str)`	`UPPER(Title)`	Upper case converted string of input parameter
URL	`URL(str)`	`URL(Column)`	Convert to a hyperlink if it is a valid URL

Name	Syntax	Sample	Output
IF	`IF(expr, successCase, [failCase])`	`IF(Column > 1, Value1, Value2)`	successCase if `expr` evaluates to TRUE, elseCase otherwise
SWITCH	`SWITCH(expr, [pattern, value, ..., default])`	`SWITCH(Column1, 1, 'One', 2, 'Two', '--')`	Switch case value based on `expr` output
AND	`AND(expr1, [expr2,...])`	`AND(Column > 2, Column < 10)`	TRUE if all `expr` evaluate to TRUE
OR	`OR(expr1, [expr2,...])`	`OR(Column > 2, Column < 10)`	TRUE if at least one `expr` evaluates to TRUE

Logical operators, along with Numerical operators can be used to build conditional expressions.

Examples:

IF(marksSecured > 80, "GradeA", "GradeB")

SWITCH(quarterNumber,  
    1, 'Jan-Mar',
    2, 'Apr-Jun',
    3, 'Jul-Sep',
    4, 'Oct-Dec',
    'INVALID'
)
