Struct astro_float_num::Consts

pub struct Consts { /* private fields */ }

Constants cache contains arbitrary-precision mathematical constants.

Implementations

impl Consts

In an ideal situation, the Consts structure is initialized with Consts::new only once, and then used where needed.

pub fn new() -> Result<Self, Error>

Initializes the constants cache.

Errors

• MemoryAllocation: failed to allocate memory for mantissa.

pub fn pi(&mut self, p: usize, rm: RoundingMode) -> BigFloat

Returns the value of the pi number with precision p using rounding mode rm. Precision is rounded upwards to the word size.

pub fn e(&mut self, p: usize, rm: RoundingMode) -> BigFloat

Returns the value of the Euler number with precision p using rounding mode rm. Precision is rounded upwards to the word size.

pub fn ln_2(&mut self, p: usize, rm: RoundingMode) -> BigFloat

Returns the value of the natural logarithm of 2 with precision p using rounding mode rm. Precision is rounded upwards to the word size.

pub fn ln_10(&mut self, p: usize, rm: RoundingMode) -> BigFloat

Returns the value of the natural logarithm of 10 with precision p using rounding mode rm. Precision is rounded upwards to the word size.
