Editing C (programming language) (section)

===Used for computationally-intensive libraries===
C enables programmers to create efficient implementations of algorithms and data structures, because the layer of abstraction from hardware is thin, and its overhead is low, an important criterion for computationally intensive programs. For example, the [[GNU Multiple Precision Arithmetic Library]], the [[GNU Scientific Library]], [[Mathematica]], and [[MATLAB]] are completely or partially written in C.  Many languages support calling library functions in C, for example, the [[Python (programming language)|Python]]-based framework [[NumPy]] uses C for the high-performance and hardware-interacting aspects.
