π/8

Minimum possible normal power of 10 exponent. Use `f64::MIN_10_EXP` instead.

1/sqrt(3)

A SIMD vector with four elements of type `u32`.

This macro handles automatic differentiation. Automatic Differentiation macro which allows generating a new function to compute the derivative of a given function. It may only be applied to a function. The expected usage syntax is `#[autodiff(NAME, MODE, INPUT_ACTIVITIES, OUTPUT_ACTIVITY)]` where: NAME is a string that represents a valid function name. MODE is any of Forward, Reverse, ForwardFirst, ReverseFirst. INPUT_ACTIVITIES consists of one valid activity for each input parameter. OUTPUT_ACTIVITY must not be set if we implicitly return nothing (or explicitly return `-> ()`). Otherwise it must be set to one of the allowed activities.

Creates an array `[T; N]` where each fallible array element `T` is returned by the `cb` call. Unlike `from_fn`, where the element creation can’t fail, this version will return an error if any element creation was unsuccessful.

Loads the current value of the pointer. `T` must be an integer or pointer type.

Maximum with the current value using a signed comparison. `T` must be a signed integer type.

Stores a value if the current value is the same as the `old` value. `T` must be an integer or pointer type.

An unwind action that continues unwinding.
