fn negative_one() -> Self

Build and return the (floating point) value -1. represented by the proper type.

fn one_div_2() -> Self

Build and return the (floating point) value 0.5 represented by the proper type.

fn pi() -> Self

Build and return the (floating point) value π represented by the proper type.

fn two_pi() -> Self

Build and return the (floating point) value 2 π represented by the proper type.

fn pi_div_2() -> Self

Build and return the (floating point) value π/2 represented by the proper type.

fn two() -> Self

Build and return the (floating point) value 2. represented by the proper type.

fn max_finite() -> Self

Build and return the maximum finite value allowed by the current floating point representation.

fn min_finite() -> Self

Build and return the minimum finite (i.e., the most negative) value allowed by the current floating point representation.

fn ln_2() -> Self

Build and return the natural logarithm of 2, i.e. the (floating point) value ln(2), represented by the proper type.

fn ln_10() -> Self

Build and return the natural logarithm of 10, i.e. the (floating point) value ln(10), represented by the proper type.

fn log10_2() -> Self

Build and return the base-10 logarithm of 2, i.e. the (floating point) value Log_10(2), represented by the proper type.

fn log2_10() -> Self

Build and return the base-2 logarithm of 10, i.e. the (floating point) value Log_2(10), represented by the proper type.

fn log2_e() -> Self

Build and return the base-2 logarithm of e, i.e. the (floating point) value Log_2(e), represented by the proper type.

fn log10_e() -> Self

Build and return the base-10 logarithm of e, i.e. the (floating point) value Log_10(e), represented by the proper type.

fn e() -> Self

Build and return the (floating point) value e represented by the proper type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
