30,057 projects in the catalog.

Free Pascal, Lazarus and Delphi components, libraries and programs from GitHub, SourceForge, Codeberg, GitLab and more. Rate them, mark what looks interesting, and talk about them on their benches.

CrossGraph

A plotting engine and a visual component that draw what MathParser computes: curves with their discontinuities, intersections and extrema, cartesian and polar systems, and surfaces z = f(x, y) with contour lines. The engine samples on worker threads, knows nothing about a canvas and builds headless; the component is a thin layer over it. Free Pascal 3.2.2 and newer builds it: the sort in CrossVision.Geometry that once needed function references is written out in the same unit. Delphi 10.2 Tokyo and newer builds it as well.

Foreval

Foreval is parser, compiler and evaluator of mathematical expressions in run-time with support complex numbers. After parsing and building tree of expression is perform optimization and compiling into x86-32 instructions and returns address of compiled expression. For expressions can by finding derivatives by symbolic or numerical differentiation.
