Implementations

impl Decimal32

pub fn zero() -> Decimal32

Constructs a 128-bit decimal floating-point number representing the number 0.

pub fn from_le_bytes(mut bytes: [u8; 4]) -> Decimal32

Creates a number from its representation as a little-endian byte array.

pub fn from_be_bytes(mut bytes: [u8; 4]) -> Decimal32

Creates a number from its representation as a big-endian byte array.

pub fn from_ne_bytes(bytes: [u8; 4]) -> Decimal32

Creates a number from its representation as a byte array in the native endianness of the target platform.

pub fn to_le_bytes(&self) -> [u8; 4]

Returns the memory representation of the number as a byte array in little-endian order.

pub fn to_be_bytes(&self) -> [u8; 4]

Returns the memory representation of the number as a byte array in big-endian order.

pub fn to_ne_bytes(&self) -> [u8; 4]

Returns the memory representation of the number as a byte array in the native endianness of the target platform.

pub fn exponent(&self) -> i32

Computes the exponent of the number.
