# A+B+C

## DMath: A+B+C

## Adds together A, B and C

## Purpose

Use this function to:

- Calculate the sum of (A, B and C)

## Return Value

| Property | Value |
| --- | --- |
| **FieldType** | Double |
| **FieldSize** | Low / Med / High / Continuous |
| **DataType** | Discrete / Continuous |
| **DataSize** | Short / Integer / LongInteger / Double |

```shell
Example Return Value: X*.XXXXXX....-X*.XXXXX

e.g.  21.000000, 98754654.123456, -5.000000, -654.320000
```

Record set displayThe result of DMATH(A+B+C) is a floating point field.   The recordset viewer only displays decimals where there is at least 1 non zero decimal digit.   Consider using LMATH(A+B+C) if no input fields have decimal precision.

## Parameters

| Parameter | JSON | Description |
| --- | --- | --- |
| **Table** | “targetTable”: “MyTableName” | The target table on which the new field will be created |
| **Filter** | “dataset”: {DataSet_JSON} | Optional. If a filter is applied, records not in the filter recordset will be returned as null. |
| **Math** **Function** | “p1”: “A+B+C” | A+B+C |
| **A** | “p2”: “NumericFieldName” “p2”: “#N*.N*” | Required. Numeric Input for A. *Supports:* - **DataType:** Discrete / Continuous - **Field Type:** Integer, Double - **Fixed Value:** #N* e.g. #201596, #-87 - **Fixed Value:** #N*.N* e.g. #201596.05, #-87.98 |
| **B** | “p3”: “NumericFieldName” “p3”: “#N*.N*” | Required. Numeric Input for B *Supports:* - **DataType:** Discrete / Continuous - **Field Type:** Integer, Double - **Fixed Value:** #N* e.g. #201596, #-87 - **Fixed Value:** #N*.N* e.g. #201596.05, #-87.98 |
| **C** | “p4”: “NumericFieldName” “p4”: “#N*.N*” | Required. Numeric Input for C. *Supports:* - **DataType:** Discrete / Continuous - **Field Type:** Integer, Double - **Fixed Value:** #N* e.g. #201596, #-87 - **Fixed Value:** #N*.N* e.g. #201596.05, #-87.98 |
| **Treat Null as Zero** | "nullIsZero": true "nullIsZero": false | True/False. Default = False If true, then any null values in the input fields will be treated as if they have a value of 0. |
