Class RandomFloat

java.lang.Object
org.pipservices3.commons.random.RandomFloat
public class RandomFloat extends Object
Random generator for float values.

### Example ### 

 
 float value1 = RandomFloat.nextFloat(5, 10);     // Possible result: 7.3
 float value2 = RandomFloat.nextFloat(10);        // Possible result: 3.7
 float value3 = RandomFloat.updateFloat(10, 3);   // Possible result: 9.2

  • Method Details

    • nextFloat

      public static float nextFloat(int max)
      Generates a float in the range [0, 'max'].
      Parameters:
      max - (optional) maximum value of the float that will be generated.
      Returns:
      generated random float value.

    • nextFloat

      public static float nextFloat(float min, float max)
      Generates a float in the range ['min', 'max']. If 'max' is omitted, then the range will be set to [0, 'min'].
      Parameters:
      min - minimum value of the float that will be generated. If 'max' is omitted, then 'max' is set to 'min' and 'min' is set to 0.
      max - (optional) maximum value of the float that will be generated. Defaults to 'min' if omitted.
      Returns:
      generated random float value.

    • updateFloat

      public static float updateFloat(float value)
      Updates (drifts) a float value without specified range defined
      Parameters:
      value - a float value to drift.
      Returns:
      updated random float value.

    • updateFloat

      public static float updateFloat(float value, float range)
      Updates (drifts) a float value within specified range defined
      Parameters:
      value - a float value to drift.
      range - (optional) a range. Default: 10% of the value
      Returns:
      updated random float value.
