bytes = Bytes[0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00]
Float64.from_be_bytes(bytes)
# => 12.5
Source
from_bytes(bytes : Bytes, format : IO::ByteFormat = IO::ByteFormat::SystemEndian) : Float64

Create a Float64 value from its representation as a byte array.

Source
from_le_bytes(bytes : Bytes) : Float64

Create a Float64 value from its representation as a byte array in little endian.

bytes = Bytes[0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x29, 0x40]
Float64.from_le_bytes(bytes)
# => 12.5

Instance methods

to_be_bytes

Return the memory representation of this number as a byte array in big-endian (network) byte order.

bytes = "12.5".to_be_bytes
# => Bytes[0x40, 0x29, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00]
Source
to_bytes(format : IO::ByteFormat = IO::ByteFormat::SystemEndian) : Bytes

Return the memory representation of this number as a byte array using the specified format

Source
