Arithmetic Operators

We've encountered an issue exporting this macro. Please try exporting this page again later.

SIL supports the standard operators (+, -, *, /, %), however, those operators can be used on more than just numbers.

Example 1 - Basic numbers

number surcharge = 2.50;
number rebate = 1.00;
number discount = 10;
number total = 10;

total = total + surcharge;
total = total - rebate;
total = total - (total * (discount/100));

return total;

Example 2 - Strings

string someText = "Hello ";
someText = someText + "World!";
someText = someText - "World";
return someText;

//returns "Hello !";

Example 3 - Dates

date duration = (dueDate + "2w") - startDate;

Example 4 - Intervals

interval day = "24h";
interval month = day * 30;
