a) The module includes the basic mathematical operators:
fieldname1+fieldname2
fieldname1*fieldname2
fieldname1/fieldname2
fieldname1-fieldname2
or mathematical equations with multiple fields and fields grouping included.
fieldname1*(fieldname2+fieldname3)

| tan(x) | Returns the tangent of an angle | If the value of fieldname1 is 90, the result of: tan(fieldname1) would be -1.995200412208242 |
Pay special attention to the next two operations. The first of them, very extended its use in equations for calculations the cost of products and services, and the other one to obtain a date.
| Operation | Description | Demo |
| prec(x,y) | Return the x number with y decimal digits | If the value of fieldname1 is 10.33323, the result of: prec(fieldname1,2) would be 10.33 If the value of fieldname1 is 10.3365, the result of: prec(fieldname1,2) would be 10.34 If the value of fieldname1 is 10, the result of: prec(fieldname1,2) would be 10.00 |
| cdate(x, format) | Returns the number x formatted like a Date, the second parameter defines the format of the output date ('mm/dd/yyyy', 'dd/mm/yyyy'). The number represents the number of days from Jan 1, 1970 | If fieldname1 is a date field, and its value is 3/11/2013: cdate(fieldname1+10) would be 13/11/2013 |
Sample valid equations:
To calculate the monthly payment in a lease calculator:
The fields implied are:
Load amount: fieldname1
Residual value: fieldname2
Interest rate %: fieldname3
Number of months: fieldname4
The corresponding equation for monthly payment is:
prec((fieldname1*fieldname3/1200*pow(1+fieldname3/1200,fieldname4)-fieldname2*fieldname3/1200)/(pow(1+fieldname3/1200,fieldname8)-1),2)
The logical module include the following functions:
| Function | Description | Demo |
| IF(condition, value if true, value if false) | Checks whether a condition is met, and returns one value if true, and another if false.IF(logical_test, value_if_true, value_if_false) | If the value of fieldname1 is 10 and the value of fieldname2 is 20, the result of: IF(fieldname1 < fieldname2, fieldname1, fieldname2) |
| AND(x,y,z,....) | Checks whether all arguments are true, and return true if all values are true, and false in another way. AND(logical1,logical2,...) | Suppose there are three fields, fieldname1, fieldname2 and fieldname3, with values: 10, 20 and 30 respectively, so: AND( fieldname1<100, fieldname2<100, fieldname3<100) but AND( fieldname1<100, fieldname2<100, fieldname3<25) |
| OR(x,y,z,....) | Checks whether any of arguments is true, and return true if any of values is true, and false if all values are false. OR(logical1,logical2,...) | Suppose there are three fields, fieldname1, fieldname2 and fieldname3, with values: 10, 20 and 30 respectively, so: OR( fieldname1<100, fieldname2<100, fieldname3<25) but OR( fieldname1<5, fieldname2<5, fieldname3<25) |
| NOT(x) | Changes false to true, or true to false.NOT(logical) | NOT(true) NOT(false) |
