*mathematics, numerical analysis*) The calculation of a definite integral by numerical means.**1992**, Bernard Bielecki,*SINC*, T.O. Espelid, Alan Genz, Springer,**Quadratures**for Cauchy Principal Value Integrals*Numerical Integration: Recent Developments, Software and Applications*, page 81 ↗,- Three types of SINC
**quadratures**are surveyed for the evaluation of Cauchy principal value integrals \textstyle\int_\Gamma F(t)dt /(t-x) , \textstyle x \in \Gamma, where \textstyle\Gamma is an arc in the complex plane. Under suitable assumptions on*F*, the**quadrature**errors are of order \textstyle O( e^{-c\sqrt{N}} ) , where*N*is the number of**quadrature**nodes and*c*is a constant independent of*N*.
