In addition to occurring within an assignment, type conversions also take place within an expression In an expression, you can freely mix two or more different types of data as long as they are compatible with each other For example, you can mix short and long within an expression because they are both numeric types When different types of data are mixed within an expression, they are converted to the same type, on an operation-by-operation basis The conversions are accomplished through the use of C# s type promotion rules Here is the algorithm that they define for binary operations: IF one operand is a decimal, THEN the other operand is promoted to decimal (unless it is of type oat or double, in which case an error results) ELSE IF one operand is a double, the second is promoted to double ELSE IF one operand is a oat, the second is promoted to oat ELSE IF one operand is a ulong, the second is promoted to ulong (unless it is of type sbyte, short, int, or long, in which case an error results) ELSE IF one operand is a long, the second is promoted to long ELSE IF one operand is a uint and the second is of type sbyte, short, or int, both are promoted to long ELSE IF one operand is a uint, the second is promoted to uint ELSE both operands are promoted to int There are a couple of important points to be made about the type promotion rules First, not all types can be mixed in an expression Specifically, there is no implicit conversion from float or double to decimal, and it is not possible to mix ulong with any signed integer type To mix these types requires the use of an explicit cast Second, pay special attention to the last rule It states that if none of the preceding rules applies, then all other operands are promoted to int Therefore, in an expression, all char, sbyte, byte, ushort, and short values are promoted to int for the purposes of calculation This is called integer promotion It also means that the outcome of all arithmetic operations will be no smaller than int It is important to understand that type promotions only apply to the values operated upon when an expression is evaluated For example, if the value of a byte variable is promoted to int inside an expression, outside the expression, the variable is still a byte Type promotion only affects the evaluation of an expression Type promotion can, however, lead to somewhat unexpected results For example, when an arithmetic operation involves two byte values, the following sequence occurs First, the byte operands are promoted to int Then the operation takes place, yielding an int result Thus, the outcome of an operation involving two byte values will be an int This is not what you might intuitively expect Consider the following program. c# ocr pdf How to Extract Text From Scanned PDFs using C# - YouTube

Polaroid Corporation lost 90 percent of its value from its peak price, and took 28 years to break even again, and then went into bankruptcy Avon Products stock was stagnant for 24 years, and Black & Decker took 23 years to get back to its peak price More currently, Enron peaked at $90 in August 2000 and then traded at $038 by year-end 2002 And hundreds of Internet stocks and technology stocks lost 90 percent or more of their value in just three years Even the stable stocks and growth stocks suffered substantial damage; witness what happened in the banking sector, Internet sector, automobile sector, and chemicals To look at the double speak of the mutual managers you only need to know that equity mutual fund portfolio turnover was around 15 percent in the 1950s through 1964, rose to 48 percent in the early 1970s, to 75 percent in 1983, 111 percent in 1987, dropped back to 74 percent in 1993 1994, and rose again to 90 percent in 2000 and 111. birt ean 128, birt upc-a, word gs1 128, word 2010 code 39 barcode, data matrix code in word erstellen, birt pdf 417 c# ocr pdf to text How to use OCR to extract text from PDF in ASP.NET, C#, C++, VB ...
