### Arithmetic Function Syntax

S-Docs templates support arithmetic functions for both static numbers and numeric fields. All functions should be written using standard **Salesforce math operators**. S-Docs will evaluate all functions using the standard mathematical order of operations.

To use arithmetic functions in your S-Docs templates, enclose the function within <MATH> tags.

The following example uses both static numbers and numeric fields.

<MATH>(2 + 1) / 3</MATH> <MATH>( {{!Opportunity.Num1__c}} + {{!Opportunity.Num2__c}} ) / {{!Opportunity.Num3__c}}</MATH>

#### Formatting Numbers

To format the result of your arithmetic function, use the *format-number* attribute within the <MATH> tag as shown below, but *not* within the merge fields.

<MATH format-number="#,###.##">{{!Opportunity.amount}} - {{!Opportunity.expectedrevenue}}</MATH>

### Arithmetic Functions with Date Fields

You can also use date fields or static dates within your arithmetic functions. The two main types of date math supported are:

- Adding/subtracting time from a date (useful if you'd like to future date documents)
- Evaluating days/months between dates

Both types of date math require the use of the *type="date"* attribute within your <MATH> tag.

**Adding/Subtracting Time**

To add or subtract days, months, or years from any date field, use the following syntax (where X equals the number of days, months, or years you would like to add or subtract from the value of the date field):

<MATH type="date">{{!Opportunity.createdByDate}} + DAYS(X) - MONTHS(X) + YEARS(X)</math>

**Evaluating Time Between Dates**

To evaluate the time between two dates, use the following syntax:

<MATH type="date">DaysBetween({{!Opportunity.createdByDate}},{{!Opportunity.closedate}}</MATH> <MATH type="date">MonthsBetween({{!Opportunity.createdByDate}},{{!Opportunity.closedate}}</MATH> <MATH type="date">YearsBetween({{!Opportunity.createdByDate}},{{!Opportunity.closedate}}</MATH>

#### Formatting Dates

To format the result of your arithmetic date function, use the *format-date* attribute within the <MATH> tag as shown below, but *not* within the merge fields.

<MATH type="date" format-date="M/dd/yyyy">

### Arithmetic Functions With Conditional Logic (RENDER Statements)

You can use arithmetic functions within your **conditional logic** statements. Arithmetic is processed before the value of the render statement is calculated.

<!--RENDER=((<MATH>{{!Opportunity.My_Num__c}} + {{!Opportunity.My_Num_2__c}}</MATH>) > 100) --> The sum of my numbers is more than 100! <!--ENDRENDER-->

**Rounding For Conditional Logic**

Arithmetic function results are evaluated by conditional logic statements *without* rounding, unless the *format-number* attribute is used to force the result to round.

For example, the following arithmetic function will evaluate to **False** within a conditional logic statement, since 2/3 equals 0.66666 repeating.

<math>2 / 3</math> == 0.67

Use *format-number* with **commas** for the thousands place and **periods** for decimal places (US number formatting) to round your arithmetic function results within conditional logic statements. For example, the following evaluates to **True**.

<math format-number="#,###.##">2 / 3</math> == 0.67

### DOCX Syntax

When using arithmetic functions in DOCX templates, use lowercase <math> tags and be sure to enclose the entire function within square brackets, as shown in the following example.

[<math>(2 + 1) / 3</math>] [<math>( {{!Opportunity.Num1__c}} + {{!Opportunity.Num2__c}} ) / {{!Opportunity.Num3__c}}</math>]
