| List Join This online calculator can join two csv lists by key column the same way JOIN works in SQL (inner join, left outer join, right outer join) |
| Calculating the parts given the ratio and total amount This online calculator finds part or whole measures of quantities using ratios |
| The Discrete Fourier Transform Sandbox This calculator visualizes Discrete Fourier Transform, performed on sample data using Fast Fourier Transformation. By changing sample data you can play with different signals and examine their DFT counterparts (real, imaginary, magnitude and phase graphs) |
| The area of a convex polygon from the coordinates of the vertices on the plane This online calculator calculates the area of a convex polygon from the coordinates of the vertices. A convex polygon is built from the vertices using the Jarvis March Algorithm (or Gift Wrapping Algorithm) |
| Days count in several date spans The calculator gives total number of days in date span list. Each date span is defined by start date and end date. The calculator can exclude multiple date date span intersections. |
| Complementary color This calculator shows complementary colors for entered colors |
| Angle in degrees to time units and vice versa This online calculator converts angle between degrees and time units (i.e. hours). |
| How many workdays between two dates? The calculator evaluates number of working days and holidays for a period of time. The calculator based on the U.S. federal holidays table recognised in most states. |
| Urn probability simulator This calculator simulates the urn (or box with colored balls) often used for probability problems, and can calculate probabilities of different events. |
| Bayes’ theorem This online calculator calculates posterior probabilities according to Bayes’ theorem. |
| Mean, variance and standard deviation of discrete random variable This online calculator calculates the mean, variance, and standard deviation of random variables entered in the form of a value-probability table. |
