# polynomial

Provides two implementations for evaluating polynomials.

You can import these APIs from the math package. For example:

from math.polynomial import polynomial_evaluate

## EvaluationMethod​

The evaluation method used to evaluate the polynomial.

Aliases:

• HORNER = 0: Evaluate the polynomial using Horner's method.
• ESTRIN = 1: Evaluate the polynomial using Estrin's method.

Implemented traits:

AnyType, Copyable, EqualityComparable, Movable

Methods:

### __eq__​

__eq__(self: Self, other: Self) -> Bool

Checks if the two methods are equal.

Args:

• other (Self): The other method.

Returns:

True if both methods are the same and False otherwise.

### __ne__​

__ne__(self: Self, other: Self) -> Bool

Checks if the two methods are not equal.

Args:

• other (Self): The other method.

Returns:

True if both methods are the different and False otherwise.

## polynomial_evaluate​

polynomial_evaluate[dtype: DType, simd_width: Int, coefficients: List[SIMD[dtype, simd_width]], method: EvaluationMethod](x: SIMD[dtype, simd_width]) -> SIMD[dtype, simd_width]

Evaluates the polynomial.

Parameters:

• dtype (DType): The dtype of the value.
• simd_width (Int): The simd_width of the computed value.
• coefficients (List[SIMD[dtype, simd_width]]): The coefficients.
• method (EvaluationMethod): The evaluation method used.

Args:

• x (SIMD[dtype, simd_width]): The value to compute the polynomial with.

Returns:

The polynomial evaluation results using the specified value and the constant coefficients.
