# Math processor

Performs calculation and computation operations on columns containing numbers.

The Math processor allows you to compute and calculate values from and between columns in a transformation flow.

## Math properties

Properties to configure to compute or calculate values from columns.

Configuration

| Property | Configuration |
| --- | --- |
| Function name | <ul> <li> <p><span>Add, substract, multiply, and divide</span>: Performs an operation/calculation on the column with another columnor with a fixed value: Add/sum (+), multiply (x), subtract (-), or divide(/).</p> </li> <li> <p><span>Base 10 Logarithm</span>: Computes the base 10 logarithm from the column.</p> </li> <li> <p><span>Absolute value</span>: Calculates the absolute value for all the numeric values in the column.</p> </li> <li> <p><span>Cosine</span>: Computes the trigonometric Cosine from the column.</p> </li> <li> <p><span>Exponential</span>: Calculates the exponential of the column numbers.</p> </li> <li> <p><span>Max</span>:Compares with another column or a constant and returns the largest value.</p> </li> <li><span>Min</span>: Compares with another column or a constant and returns the smallest value.</li> <li> <p><span>Modulo</span>: Calculates the remainder of a division operation.</p> </li> <li> <p><span>Natural logarithm</span>: Computes the natural logarithm from a column.</p> </li> <li> <p><span>Negate</span>: Negates the column numbers.</p> </li> <li> <p><span>Power</span>: Multiplies to the power of  another column or a constant.</p> </li> <li><span>Sine</span>: Computes the trigonometric Sine from the column numbers.</li> <li> <p><span>Square root</span>: Calculates the square  root of the column numbers.</p> </li> <li> <p><span>Tangent</span>: Computes the trigonometric Tangent from the column numbers.</p> </li> </ul> |
| Columns to process | Select the column or columns on which you want to apply a function in the list.<br><br>Information note<br><br>If you want to apply the same function to multiple columns at once, click the Open dialog icon to open a tree view that allows you to select multiple columns. |
| Create new column | Enable this option to create a new column after applying the function. If you do not enable this option, the existing column will be kept and modified. |
