Function Documentation

pow2_3()

double openswmm::fastmath::pow2_3 ( double x )

inlinenoexcept

Compute the real 2/3 power using square or cube roots.

Parameters

[in]

x

Finite input; x * x must remain representable for a finite result. Units are chosen by the caller.

Returns

cbrt(x * x); standard-library floating-point domain and range behavior applies. The result is returned by value.

pow3_2()

double openswmm::fastmath::pow3_2 ( double x )

inlinenoexcept

Compute the real 3/2 power using square or cube roots.

Parameters

[in]

x

Nonnegative finite input. Units are chosen by the caller.

Returns

x * sqrt(x); standard-library floating-point domain and range behavior applies. The result is returned by value.

pow4_3()

double openswmm::fastmath::pow4_3 ( double x )

inlinenoexcept

Compute the real 4/3 power using square or cube roots.

Parameters

[in]

x

Finite input. Units are chosen by the caller.

Returns

x * cbrt(x); standard-library floating-point domain and range behavior applies. The result is returned by value.

pow5_2()

double openswmm::fastmath::pow5_2 ( double x )

inlinenoexcept

Compute the real 5/2 power using square or cube roots.

Parameters

[in]

x

Nonnegative finite input. Units are chosen by the caller.

Returns

x * x * sqrt(x); standard-library floating-point domain and range behavior applies. The result is returned by value.

pow5_3()

double openswmm::fastmath::pow5_3 ( double x )

inlinenoexcept

Compute the real 5/3 power using square or cube roots.

Parameters

[in]

x

Finite input; x * x must remain representable for a finite result. Units are chosen by the caller.

Returns

x * cbrt(x * x); standard-library floating-point domain and range behavior applies. The result is returned by value.
