The Calculator analysis function performs mathematical operations on time series.

The mathematical operations to be performed are entered as a formula or mathematical expression. The formula is individually applied to each of the timestamps contained in the series that were selected for the analysis. The result is a new time series.

The following mathematical operators are supported:

*<code>()</code>: Parenthesis
*<code>+</code>: Addition operator e.g. <code>3 + 2</code>
*<code>-</code>: Subtraction operator e.g. <code>3 - 2</code>
*<code>*</code>: Multiplication operator e.g. <code>3 * 2</code>
*<code>/</code>: Division operator e.g. <code>3 / 2</code>
*<code>%</code>: Modulus operator e.g. <code>3 % 2</code> (divides the two numbers, but returns the remainder)
*<code>^</code>: Exponent operator e.g. <code>3 ^ 2</code>
*<code>ABS</code>: Returns the absolute of a number e.g. <code>ABS(-3)</code>
*<code>SIN</code>: Returns the sine of a number e.g. <code>SIN(3.14)</code>
*<code>COS</code>: Returns the cosine of a number e.g. <code>COS(3.14)</code>
*<code>TAN</code>: Returns the tangent of a number e.g. <code>TAN(3.14)</code>
*<code>LOG</code>: Returns the base 10 logarithm of a number e.g. <code>LOG(3)</code>
*<code>LOGN</code>: Returns the natural logarithm of a number e.g. <code>LOGN(4)</code>

Time series selected for this analysis can be added to the formula as variables either by entering the letter representing the time series manually or by double-clicking the time series in the list box.

The calculation only results in a value for those timestamps that are common to all of the time series selected for analysis. If a timestamp is missing in one or more time series or the value of one or more time series is NaN for a timestamp, the resulting time series will have a NaN value for this particular timestamp.

Examples:
* <code>100</code> (without any variables):
: results in a time series with the value of 100 for each timestamp
* <code>A / 100</code> (where A is a time series):
: results in a time series where all values of A are divided by 100
* <code>A + B</code> (where A and B are time series):
: results in a time series where the values of A and B are added to together for each common timestamp
* <code>(2 * A) + LOG(B) - ABS(C)</code> (where A, B and C are time series):
: complex calculation with multiple time series

Note: The [https://www.codeproject.com/articles/274093/math-parser-net Math Parser .NET] library is used for parsing and evaluating the mathematical expression.
