def to_bytes(format : IO::ByteFormat = IO::ByteFormat::SystemEndian) : Bytes #

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


[View source]
def to_le_bytes : Bytes #

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

bytes = 12.5.to_le_bytes
# => Bytes[0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x29, 0x40]
