 The following example illustrates the problem. It repeatedly adds .1 to 11.0 and rounds the result to the nearest integer. Regardless of the rounding convention, 11.5 should round to 12. However, as the output from the example shows, it does not. The example uses the "R" [standard numeric format string](~/docs/standard/base-types/standard-numeric-format-strings.md) to display the floating point value's full precision, and shows that the value to be rounded has lost precision during repeated additions, and its value is actually 11.499999999999998. Because .499999999999998 is less than .5, the value is not rounded to the next highest integer. As the example also shows, this problem does not occur if we simply assign the constant value 11.5 to a <xref:System.Double> variable.

  You can generate the same sequence of random numbers by providing the same seed value to the <xref:System.Random.%23ctor%28System.Int32%29> constructor. The seed value provides a starting value for the pseudo-random number generation algorithm. The following example uses 100100 as an arbitrary seed value to instantiate the <xref:System.Random> object, displays 20 random floating-point values, and persists the seed value. It then restores the seed value, instantiates a new random number generator, and displays the same 20 random floating-point values.  Note that the example may produce different sequences of random numbers if run on different versions of the .NET Framework.
