public static double ToDouble (byte[] value, int startIndex); Parameters value Byte[] An array of bytes that includes the eight bytes to convert. startIndex Int32 The starting position within value. Returns Double A double-precision floating point number formed by eight bytes beginning at...
Double指的是双精度浮点数（Double Precision Floating Point），它使用64位来存储一个数字，其中52位表示该数字的小数部分，而11位则表示指数。使用双精度浮点数的好处在于，它可以存储非常大或非常小的数值，并且可以具有一定的精度。在Matlab中，double是默认数据类型，并且通常比单精度浮点数更加精确。在...
Double-precision arrays expand all in page Description double is the default numeric data type (class) in MATLAB®, providing sufficient precision for most computational tasks. Numeric variables are automatically stored as 64-bit (8-byte) double-precision floating-point values. For example: x = ...

Round the 2 double precision floating-point values in the source operand (second operand) using the rounding mode specified in the immediate operand (third operand) and place the results in the destination operand (first operand). The rounding process rounds each input floating-point value to an...
For more information on double- and single-precision floating-point values, seeFloating-Point Numbers. Creation You create a double-precision array automatically when you assign a numeric scalar or array to a variable, such asA = [1 2 3; 4 5 6]. The variableAhas typedouble. For more infor...
Subtract the low double precision floating-point value in the second source operand from the first source operand and stores the double precision floating-point result in the low quadword of the destination operand. The second source operand can be an XMM register or a 64-bit memory location. ...
Converts two, four or eight packed double-precision floating-point values in the source operand (second operand) to two, four or eight packed single-precision floating-point values in the destination operand (first operand). When a conversion is inexact, the value returned is rounded according ...
