pub struct Consts { /* private fields */ }

Expand description

Constants cache contains arbitrary-precision mathematical constants.

Implementations

source

impl Consts

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

source

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

Initializes the constants cache.

Errors

MemoryAllocation: failed to allocate memory for mantissa.

source

pub fn pi(&mut self, p: usize, rm: RoundingMode) -> Result<BigFloatNumber, Error>

Returns the value of the pi number with precision p.

Errors

MemoryAllocation: failed to allocate memory for mantissa.
InvalidArgument: precision is incorrect.

source

pub fn e(&mut self, p: usize, rm: RoundingMode) -> Result<BigFloatNumber, Error>

Returns the value of the Euler number with precision p.

Errors

MemoryAllocation: failed to allocate memory for mantissa.
InvalidArgument: precision is incorrect.

source

pub fn ln_2(
 &mut self,
 p: usize,
 rm: RoundingMode
) -> Result<BigFloatNumber, Error>

Returns the value of the natural logarithm of 2 with precision p.

Errors

MemoryAllocation: failed to allocate memory for mantissa.
InvalidArgument: precision is incorrect.

source

pub fn ln_10(
 &mut self,
 p: usize,
 rm: RoundingMode
) -> Result<BigFloatNumber, Error>

Returns the value of the natural logarithm of 10 with precision p using rounding mode rm.

Errors

MemoryAllocation: failed to allocate memory for mantissa.
InvalidArgument: precision is incorrect.
