# Formats the given byte value into a human readable form.
#
# Accepts four optional arguments that control the output format:
#   as_bits: If true, converts the given byte value to bits and adjusts the suffix accordingly. Defaults to false.
#   binary: If true, calculates order of magnitude as base 2 (binary) instead of base 10 (decimal). Defaults to true.
#   full_suffix: If true, uses full suffix names such as "Megabyte", otherwise uses abbreviations like "MB" or "Mib". Defaults to false.
#   precision: The number of decimal points to include in the output. Trailing zero's are removed. Defaults to 2.
