EQUAL (=)


The operator '=' compares two values and returns the boolean value TRUE if the left value is equal to the right value and FALSE otherwise.


Syntax

 value1 = value2


Inputs

  • value1 - Number, date or attribute of some type of number or date.

  • value2 - Number, date or attribute of some type of number or date.


When one or both values are a set, the '=' operator is translated to SUBSET OF:

  • "a" = ["a", "b"] is equivalent to "a" SUBSET OF ["a","b"], which returns true
  • ["a", "b"] = "a" is also equivalent to "a" SUBSET OF ["a","b"], note that the arguments are switched. Because we have a set and a single value, there is only one way to interpret this with the SUBSET OF function.
  • ["a"] = ["a", "b"] is equivalent to ["a"] SUBSET OF ["a","b"], which returns true
  • ["a", "b"] = ["a"] is equivalent to ["a", "b"] SUBSET OF ["a"], which returns false. (note that if "set1 = set2" returns true, it does not mean that "set2 = set1" will also return true)

To test if two sets are equal you could use the expression:

L1 SUBSET OF L2 AND L2 SUBSET OF L1


Return type

  • boolean


Examples

ExpressionResultType
1 = 2FALSEBoolean

1.0 = 1.0

TRUEBoolean
DATE( 2012 , 1 , 1 ) = TODAYFALSEBoolean
5 + 5 = 10TRUEBoolean

NOT EQUAL (!=)


The operator '!=' compares two values and returns the boolean value TRUE if the left value is not equal to the right value and FALSE otherwise.


Syntax

 value1 != value2


Inputs

  • value1 - Number, date or attribute of some type of number or date.

  • value2 - Number, date or attribute of some type of number or date.


Return type

  • boolean


Examples

ExpressionResultType
1 != 2TRUEboolean

Inputs

  • value1 - Number, date or attribute of some type of number or date.

  • value2 - Number, date or attribute of some type of number or date.


Return type

  • boolean


Examples

GREATER (>)


The operator '>' compares two values and returns the boolean value TRUE if the left value is greater than the right value and FALSE otherwise.


Syntax

 value1 > value2


Inputs

  • value1 - Number, date or attribute of some type of number or date.

  • value2 - Number, date or attribute of some type of number or date.


Return type

  • boolean

ANNUITY


Computes an annuity. An annuity is a terminating "stream" of fixed payments, i.e., a collection of payments to be periodically received over a specified period of time.

It is computed using this formula:

where

  • J = monthly payment
  • i = rate of interest
  • n = number of terms
  • T = loan amount


Syntax

 ANNUITY ( loan_amount , interest_rate , number_of_terms )


Inputs

  • loan_amount - The total currency amount that should be paid back.

  • interest_rate - The interest rate as type percentage that should be paid on a loan (As a fraction, e.g. 5% = 0.05)

  • number_of_terms - The number of terms as integer.


Return type

  • number - The monthly payment.


Examples

ExpressionResultType
ANNUITY ( 1000 , 0.05 , 12 )112.8254Number
ANNUITY ( 1000 , 0.05 , 1 )1050Number

    I noticed an issue with the DIV-function.


    Microsoft Excel's QUOTIENT-function has the exact same description ("Returns the integer portion of a division"),

    However both give different results:


    XYX DIV YQUOTIENT( X ; Y )
    000#DIV/0!
    309223372036854775807#DIV/0!
    37-10-4-3
    -3710-4-3
