Computation :: Data Encoding

b64_to_bytes(b64): Returns a string of raw bytes, 8 bits each. b64 strings with characters outside of the RFC 3548 standard or with excess padding characters at the end will not decode correctly.

bin_to_bytes(bin): Returns a string of raw bytes (8 bits each) representing the given binary string.

bytes_to_b64(str): Returns a string of base64 digits (RFC 3548), 6 bits each.

bytes_to_bin(str): Returns a string of binary digits, 1 bit each.

bytes_to_hex(str): Returns a string of hexadecimal digits, 4 bits each.

decode_real_double(str): Returns a real value decoded from the given string of raw bytes in IEEE 754 double precision format.

encode_real_double(n): Returns a string of raw bytes representing the given number encoded in IEEE 754 double precision format.

hex_to_bytes(hex): Returns a string of raw bytes (8 bits each) representing the given hexadecimal string.

value_min_bits(n,size): Returns the smallest number of words of a given size that can be used to store a given value.

word_max_value(length,size): Returns the largest unsigned integer that can be stored in a given number of words of a given size.
