Finding Net Gains or Losses How do I calculate the percentage gain or loss for my portfolio when all of the stocks have different prices? Finding the total percentage gain or loss on a portfolio requires a few simple calculations. First, you should understand how percentage gains or losses are found on an individual security. To find the net gain or loss, subtract the purchase price from the current price and divide the difference by the purchase prices of the asset.

- There're at least four different ways doing this conversion. Encoding's GetString. , but you won't be able to get the original bytes back if those bytes have non-ASCII characters. BitConverter.ToString. The output is a - delimited string, but there's no .NET built-in method to convert the string back to byte array. Convert.ToBase64String. You can easily convert the output string back to byte array by using Convert.FromBase64String. Note: The output string could contain '+', '/' and '='. If you want to use the string in a URL, you need to explicitly encode it.

- I had no idea you could just use 'atoi' on a character array. ...my 'plan B' was to use the WString library, and convert the character array into a string, then the string into an integer...totally inefficient and space consuming, especially since I only have an atmega168 with my board. Edit: @lloyddean: Thanks for your input also, It works perfectly also.

- It depends what is the character and what encoding it is in: 1  An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits. 2  An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte). 3  A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes). A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits.

How to convert UTF-8 data into a String admin November 27, 2012 Software Development Kits No Comments. If you have an array of UTF-8 bytes and want to convert them into a String then the following may help…. As you may know, UTF-8 is a way of encoding every character in the Unicode character set using a variable number of byte per character.

Convert String to ByteArray Note: You need to take the encoding into account, because one character could be represented by one or more bytes (it may be up to about 6), and different encodings will treat these bytes in a different way. Strings are stored with two bytes per character. ASCII only allows one byte per character.

Convert a string into a byte array in VB.NET .NET offers a class for each type of encoding in the System.Text namespace. To perform encoding of a string into a byte array, you need to use an appropriate encoding object and then call its GetBytes method. See the example in Listing A.

Convert Integer to Byte Array in C# The BitConverter class has a static overloaded GetBytes method that takes an integer, double or other base type value and convert that to a array of bytes. The BitConverter class also have other static methods to reverse this conversion. Some of these methods are ToDouble, ToChart, ToBoolean, ToInt16, and ToSingle.

Convert from Character Arrays to Numeric Values The functions listed in this table provide a number of ways to convert character strings to numeric data. Function. Description. Example. uintN (e.g., uint8). Convert a character to an integer code that represents that character. 'Hi' → 72 105. str2num. Convert a character type to a numeric type. '72 105' → [72 105]. str2double. Similar to str2num, but offers better performance and works with cell arrays of strings.

Introduction to Unicode Â¶ The rules for converting a Unicode string into the ASCII encoding are simple; for each code point: 1  If the code point is < 128, each byte is the same as the value of the code point.  If the code point is 128 or greater, the Unicode string can’t be represented in this encoding. (Python raises a exception in this case.)

Working with Strings Unicode is the preferred character encoding, because it supports all character sets and languages. Windows represents Unicode characters using UTF-16 encoding, in which each character is encoded as a 16-bit value. UTF-16 characters are called wide characters, to distinguish them from 8-bit ANSI characters.

Comparison of Unicode encodings The first 128 Unicode code points, U+0000 to U+007F, used for the C0 Controls and Basic Latin characters and which correspond one-to-one to their ASCII-code equivalents, are encoded using 8 bits in UTF-8, 16 bits in UTF-16, and 32 bits in UTF-32.

2. Built-in Functions Â¶ bytearray([source[, encoding[, errors]]]). The optional source parameter can be used to initialize the array in a few different ways: If it is a string, you must also give the encoding (and optionally, errors) parameters; bytearray() then converts the string to bytes using str.encode().

CAST and CONVERT (Transact-SQL) Because Unicode data always uses an even number of bytes, use caution when you convert binary or varbinary to or from Unicode supported data types. For example, the following conversion does not return a hexadecimal value of 41; it returns 4100: SELECT CAST(CAST(0x41 AS nvarchar) AS varbinary).

Insert ASCII or Unicode Latin-based symbols and characters ASCII and Unicode character encoding enables computers to store and exchange data with other computers and programs. Below are lists of frequently used ASCII and Unicode Latin-based characters. For Unicode characters for non-Latin-based scripts, see Unicode character code charts by script. In this article.
