The Interpolation Calculator estimates values between known data points using several methods. Choose from linear interpolation between two points, bilinear interpolation on a 2D grid, piecewise linear interpolation from a data table, or Lagrange polynomial interpolation.
Enter your data points and target x value to get the interpolated result with detailed step-by-step working. The data table and Lagrange modes include an SVG scatter plot showing your data points and the interpolated value.
