It depends what is the character and what encoding it is in: An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits. An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte). A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and … Read more
You can use the Blob to get the string size in bytes. Examples: console.info( new Blob([‘😂’]).size, // 4 new Blob([‘👍’]).size, // 4 new Blob([‘😂👍’]).size, // 8 new Blob([‘👍😂’]).size, // 8 new Blob([‘I\’m a string’]).size, // 12 // from Premasagar correction of Lauri’s answer for // strings containing lone characters in the surrogate pair range: // … Read more
The b prefix signifies a bytes string literal. If you see it used in Python 3 source code, the expression creates a bytes object, not a regular Unicode str object. If you see it echoed in your Python shell or as part of a list, dict or other container contents, then you see a bytes … Read more
You can use: File.WriteAllBytes(“Foo.txt”, arrBytes); // Requires System.IO If you have an enumerable and not an array, you can use: File.WriteAllBytes(“Foo.txt”, arrBytes.ToArray()); // Requires System.Linq
The byte keyword is an alias for the System.Byte data type. They represent the same data type, so the resulting code is identical. There are only some differences in usage: You can use byte even if the System namespace is not included. To use Byte you have to have a using System; at the top … Read more
From this: (source) Unminified and ES6’ed: (by the community) function formatBytes(bytes, decimals = 2) { if (!+bytes) return ‘0 Bytes’ const k = 1024 const dm = decimals < 0 ? 0 : decimals const sizes = [‘Bytes’, ‘KB’, ‘MB’, ‘GB’, ‘TB’, ‘PB’, ‘EB’, ‘ZB’, ‘YB’] const i = Math.floor(Math.log(bytes) / Math.log(k)) return `${parseFloat((bytes / … Read more
You can use encoding like ASCII to get a character per byte by using the System.Text.Encoding class. or try this System.Text.ASCIIEncoding.Unicode.GetByteCount(string); System.Text.ASCIIEncoding.ASCII.GetByteCount(string);
Have a look at the ByteBuffer class. ByteBuffer b = ByteBuffer.allocate(4); //b.order(ByteOrder.BIG_ENDIAN); // optional, the initial order of a byte buffer is always BIG_ENDIAN. b.putInt(0xAABBCCDD); byte[] result = b.array(); Setting the byte order ensures that result[0] == 0xAA, result[1] == 0xBB, result[2] == 0xCC and result[3] == 0xDD. Or alternatively, you could do it manually: … Read more
Assuming you’re on at least 3.2, there’s a built in for this: int.from_bytes( bytes, byteorder, *, signed=False ) … The argument bytes must either be a bytes-like object or an iterable producing bytes. The byteorder argument determines the byte order used to represent the integer. If byteorder is “big”, the most significant byte is at … Read more
From S. Prakash, found at the MySQL forum: SELECT table_schema “database name”, sum( data_length + index_length ) / 1024 / 1024 “database size in MB”, sum( data_free )/ 1024 / 1024 “free space in MB” FROM information_schema.TABLES GROUP BY table_schema; Or in a single line for easier copy-pasting: SELECT table_schema “database name”, sum( data_length + … Read more
