Enum ATan2InputErrors 

pub enum ATan2InputErrors<RawReal: RawRealTrait> {
    InvalidNumerator {
        source: <RawReal as RawScalarTrait>::ValidationErrors,
    },
    InvalidDenominator {
        source: <RawReal as RawScalarTrait>::ValidationErrors,
    },
    ZeroOverZero {
        backtrace: Backtrace,
    },
}

Errors that can occur during the input validation phase when attempting to compute the 2-argument arctangent (atan2).

This enum is used as a source for the Input variant of ATan2Errors. It is generic over RawReal: RawRealTrait, which defines the specific raw real number type (via RawReal: RawRealTrait) and its associated validation error type (via <RawReal as RawScalarTrait>::ValidationErrors) for the numerator and denominator inputs.

atan2(y, x) computes the principal value of the arctangent of y/x, using the signs of both arguments to determine the quadrant of the result.

Variants

InvalidNumerator

The numerator (y in atan2(y, x)) failed basic validation checks.

This error occurs if the numerator itself is considered invalid according to the validation policy (e.g., StrictFinitePolicy), such as being NaN or Infinity.

Fields

source: <RawReal as RawScalarTrait>::ValidationErrors

The underlying validation error from the numerator’s raw real type.

InvalidDenominator

The denominator (x in atan2(y, x)) failed basic validation checks.

This error occurs if the denominator itself is considered invalid according to the validation policy (e.g., StrictFinitePolicy), such as being NaN or Infinity.

Fields

source: <RawReal as RawScalarTrait>::ValidationErrors

The underlying validation error from the denominator’s raw real type.

ZeroOverZero

Both the numerator (y) and the denominator (x) are zero.

The atan2(0, 0) case is undefined or implementation-specific in many contexts. This library considers it an error.

Fields

backtrace: Backtrace
