+\section ccmathintro Introduction to ccmath library
+
+A mathematics library coded in the C-language containing functions for linear algebra, numerical integration, geometry and trigonometry, curve fitting, roots and optimization, Fourier analysis, simulation generation, statistics, special functions, sorts and searches, time series models, complex arithmetic, and high precision math.
+
+Note: reduces version included in GRASS GIS:
