floating point to decimal example

Der Decimal von dieser Methode zurückgegebene Wert enthält maximal sieben signifikante Ziffern.The Decimal value returned by this method contains a maximum of seven significant digits. Konvertiert den Wert des angegebenen Objekts in eine entsprechende Dezimalzahl. Separate into the sign, exponent, and mantissa fields. Ein Objekt, das die IConvertible-Schnittstelle implementiert, oder null.An object that implements the IConvertible interface, or null. Ein Objekt, das die IConvertible-Schnittstelle implementiert.An object that implements the IConvertible interface. Im folgenden Beispiel wird ein- Double Wert in einen- Decimal Wert konvertiert.The following example converts a Double value to a Decimal value. The advantage of using a fixed-point representation is performance and disadvantage is  relatively limited range of values that they can represent. Im folgenden Beispiel wird veranschaulicht, wie die- ToDecimal(Single) Methode Rundungen zum nächsten verwendet, um einen Decimal Wert mit sieben signifikanten Ziffern zurückzugeben.The following example illustrates how the ToDecimal(Single) method uses rounding to nearest to return a Decimal value with seven significant digits. Die Zahl 1, wenn valuetrue ist, andernfalls 0 (null).The number 1 if value is true; otherwise, 0. Only the mantissa m and the exponent e are physically represented in the register (including their sign). provider ermöglicht es dem Benutzer, kulturspezifische Konvertierungs Informationen zum Inhalt von anzugeben value .provider enables the user to specify culture-specific conversion information about the contents of value. value wird mithilfe der Formatierungskonventionen der aktuellen Threadkultur interpretiert.value is interpreted by using the formatting conventions of the current thread culture. As example in number 34.890625, the integral part is the number in front of the decimal point (34), the fractional part is the rest after the decimal point (.890625). A string that contains a number to convert. The rules for converting a floating point number into decimal are simply to reverse of the decimal to floating point conversion: If the original number is in hex, convert it to binary. Then, -43.625 is represented as following: Where, 0 is used to represent + and 1 is used to represent. Die zu konvertierende 8-Bit-Ganzzahl ohne Vorzeichen. Konvertiert den Wert der angegebenen 16-Bit-Ganzzahl ohne Vorzeichen in eine entsprechende Dezimalzahl. Der Rückgabewert ist das Ergebnis des Aufrufs der- Decimal.Parse Methode für value .The return value is the result of invoking the Decimal.Parse method on value. Konvertiert den Wert der angegebenen 64-Bit-Ganzzahl ohne Vorzeichen in eine entsprechende Dezimalzahl.Converts the value of the specified 64-bit unsigned integer to an equivalent decimal number. The fixed point mantissa may be fraction or an integer. The following example tries to convert each element in an array of Single values to a Decimal value. There are two major approaches to store real numbers (i.e., numbers with fractional component) in modern computing. Konvertiert den angegebenen booleschen Wert in die entsprechende Dezimalzahl.Converts the specified Boolean value to the equivalent decimal number. This representation does not reserve a specific number of bits for the integer part or the fractional part. All the exponent bits 1 and mantissa bits non-zero represents error. Converts the value of the specified 16-bit signed integer to an equivalent decimal number. Die zu konvertierende 64-Bit-Ganzzahl ohne Vorzeichen. An object that supplies culture-specific formatting information. Konvertiert den Wert der angegebenen 64-Bit-Ganzzahl mit Vorzeichen in eine entsprechende Dezimalzahl. Die zu konvertierende 8-Bit-Ganzzahl mit Vorzeichen. Konvertiert den Wert der angegebenen Gleitkommazahl mit doppelter Genauigkeit in eine entsprechende Dezimalzahl.Converts the value of the specified double-precision floating-point number to an equivalent decimal number. The second part of designates the position of the decimal (or binary) point and is called the exponent. Konvertiert den Wert der angegebenen 16-Bit-Ganzzahl mit Vorzeichen in eine entsprechende Dezimalzahl.Converts the value of the specified 16-bit signed integer to an equivalent decimal number. Konvertiert den Wert der angegebenen 8-Bit-Ganzzahl mit Vorzeichen in die entsprechende Dezimalzahl. Converts the value of the specified object to an equivalent decimal number. Die Verwendung der- ToDecimal(String) Methode entspricht der Übergabe value an die- Decimal.Parse(String) Methode.Using the ToDecimal(String) method is equivalent to passing value to the Decimal.Parse(String) method. Where 00000101 is the 8-bit binary value of exponent value +5. Konvertiert den Wert der angegebenen 32-Bit-Ganzzahl mit Vorzeichen in eine entsprechende Dezimalzahl.Converts the value of the specified 32-bit signed integer to an equivalent decimal number. Das- NumberFormatInfo Objekt stellt kulturspezifische Informationen zum Format von bereit value .The NumberFormatInfo object provides culture-specific information about the format of value. A decimal number that is equivalent to the number in, Im folgenden Beispiel wird die Verwendung von, The following example illustrates the use of, Wenn eine Ausnahme nicht behandelt werden soll, wenn bei der Konvertierung ein Fehler auftritt, können Sie stattdessen die-Methode aufzurufen, If you prefer not to handle an exception if the conversion fails, you can call the.
