# Polynomial evaluation Evaluate polynomials using coefficients and independent variables that you supply. ## Topics ### Single-precision polynomial evaluation [`static func evaluatePolynomial(usingCoefficients: [Float], withVariables: U) -> [Float]`](/documentation/Accelerate/vDSP/evaluatePolynomial(usingCoefficients:withVariables:)-7mznu) Returns a single-precision evaluated polynomial using specified coefficients and variables. [`static func evaluatePolynomial(usingCoefficients: [Float], withVariables: U, result: inout V)`](/documentation/Accelerate/vDSP/evaluatePolynomial(usingCoefficients:withVariables:result:)-6eaoc) Evaluates a single-precision polynomial using specified coefficients and variables. [`extern void vDSP_vpoly(const float *__A, vDSP_Stride __IA, const float *__B, vDSP_Stride __IB, float *__C, vDSP_Stride __IC, vDSP_Length __N, vDSP_Length __P);`](/documentation/Accelerate/vDSP_vpoly) Evaluates a single-precision polynomial using specified coefficients, variables, and strides. ### Double-precision polynomial evaluation [`static func evaluatePolynomial(usingCoefficients: [Double], withVariables: U) -> [Double]`](/documentation/Accelerate/vDSP/evaluatePolynomial(usingCoefficients:withVariables:)-31vi2) Returns a double-precision evaluated polynomial using specified coefficients and variables. [`static func evaluatePolynomial(usingCoefficients: [Double], withVariables: U, result: inout V)`](/documentation/Accelerate/vDSP/evaluatePolynomial(usingCoefficients:withVariables:result:)-2ncdh) Evaluates a double-precision polynomial using specified coefficients and variables. [`extern void vDSP_vpolyD(const double *__A, vDSP_Stride __IA, const double *__B, vDSP_Stride __IB, double *__C, vDSP_Stride __IC, vDSP_Length __N, vDSP_Length __P);`](/documentation/Accelerate/vDSP_vpolyD) Evaluates a double-precision polynomial using specified coefficients, variables, and strides. --- Copyright © 2026 Apple Inc.
