## Configure Math FX

Connect the Math FX node to the Select tables of the relevant table. Go to the Properties panel and set the preferences for the mathematical function:

**Select Column:** choose the column to which the mathematical function will be applied.

**Function Type:** choose the mathematical function to apply to the column.

**Column Output:** determine whether or not to keep the original column.

**New Column Name:** name the new column.

### Function Type

The Math FX node enables the following mathematical functions:

- Absolute Value: returns the absolute value of a number.
- Ceiling: returns the smallest integer greater than or equal to a given number.
- Floor: returns the largest integer less than or equal to a given number.
- Exponent: returns the number 'e' or Euler's number, raised to the power of the provided value.
- Log: returns the natural logarithm (base e) of a number.
- Power: returns the base number to the exponent power.
- Root:
- Round: returns the value of a number rounded to the nearest integer.

The Overhead column contains decimal values. To produce a column without decimals, the Ceiling function is applied to return the smallest integer that is greater that or equal to the current value:
