# Math

Name Description
Abs(​Decimal) Returns the absolute value (unsigned magnitude) of the decimal number 'n'.
Mod(​Decimal, Decimal) Returns the remainder of decimal division of 'n' by 'm'.
Power(​Decimal, Decimal) Returns 'n' raised to the power of 'm'.
Round(​Decimal, Integer) Returns the Decimal number 'n' rounded to a specific number of 'fractional digits'.
The round method applied depends on where the function is used:
- In expressions in client-side and server-side logic, applies the method round half to even (rounds to the nearest integer, 0.5 rounds to the nearest even integer).
- In aggregates that query SQL Server or Oracle databases, applies the method round half away from 0 (rounds to the nearest integer, 0.5 rounds the number further away from 0).
- In aggregates that query MySQL or iDB2 databases, applies the method round half up (rounds to the nearest integer, 0.5 rounds up).
Sqrt(​Decimal) Returns the square root of the Decimal number 'n'.
Trunc(​Decimal) Returns the Decimal number 'n' truncated to integer removing the decimal part of 'n'.

m
Type: Decimal. Mandatory.
The divisor in the modulo operation.
Output

Type: Decimal

Examples

`Mod(10, 3) = 1Mod(4, 3.5) = 0.5`

## Power

Returns 'n' raised to the power of 'm'.

Available in:

• Server-side logic: Yes

Output

Type: Decimal

Examples

`Power(100, 2) = 10000Power(-10.89, 2.3) = 0Power(-10.89, -5) = -6.52920946044017E-06`

## Round

Returns the Decimal number 'n' rounded to a specific number of 'fractional digits'.
The round method applied depends on where the function is used:
- In expressions in client-side and server-side logic, applies the method round half to even (rounds to the nearest integer, 0.5 rounds to the nearest even integer).
- In aggregates that query SQL Server or Oracle databases, applies the method round half away from 0 (rounds to the nearest integer, 0.5 rounds the number further away from 0).
- In aggregates that query MySQL or iDB2 databases, applies the method round half up (rounds to the nearest integer, 0.5 rounds up).

Available in:

• Server-side logic: Yes
• Client-side logic: Yes
• Database: Can be used with attributes in aggregates.
• Local Storage: Can be used with attributes in aggregates.
Parameters
n
Type: Decimal. Mandatory.
The Decimal number to round
fractionalDigits
Type: Integer.
Use it to specify the number of fractional digits that n has to be rounded to. The default value is 0. Note: In aggregates this parameter is not specified.
Output

Type: Decimal

Examples

When used in expressions in client-side and server-side logic:
`Round(-10.89) = -11Round(-5.5) = -6Round(9.3) = 9Round(2.5) = 2Round(3.5) = 4Round(9.123456789, 5) = 9.12346`

When used in aggregates that query SQL Server or Oraclde database:
`Round(-10.89) = -11Round(-5.5) = -6Round(9.3) = 9Round(2.5) = 3Round(3.5) = 4`

When used in aggregates that query MySQL or iDB2 database:
`Round(-10.89) = -11Round(-5.5) = -5Round(9.3) = 9Round(2.5) = 3Round(3.5) = 4`

## Sqrt

Returns the square root of the Decimal number 'n'.

Available in:

• Server-side logic: Yes
• Client-side logic: Yes
• Database: Can be used with attributes in aggregates.
• Local Storage: Function is evaluated before the aggregate is executed.
Parameters
n
Type: Decimal. Mandatory.
The number to calculate the square root from.
Output

Type: Decimal

Examples

`Sqrt(2.3) = 1.51657508881031`

## Trunc

Returns the Decimal number 'n' truncated to integer removing the decimal part of 'n'.

Available in:

• Server-side logic: Yes
• Client-side logic: Yes
• Database: Can be used with attributes in aggregates.
• Local Storage: Can be used with attributes in aggregates.
Parameters
n
Type: Decimal. Mandatory.
