round
```
public static double round(double d,
                           int accurateDecimalPlaces,
                           int decimalPlaces,
                           int roundType)
```
Uses BigDecimal to round number to "decimalPlaces" amount of decimal numbers.
Notes:
Since doubles are floating point numbers, there is a chance for loss of precision.
For rounding, this could cause a problem when the digit that is being removed should be a 5, in which case the previous digit might need to be changed based on the type of rounding that is being performed (ex: BigDecimal.ROUND_HALF_UP, ROUND_HALF_DOWN, etc.).
Floating point numbers mostly lose precision when being used for a lot of calculations.
Example: a number "1.5" could be represented as "1.499999" or "1.500001" as a double.
The round method allows you to specify the number of decimal places that you know the number currently should have. The round method will first round the number to this amount of decimal places before performing the round. SEE: https://stackoverflow.com/questions/2808535/round-a-double-to-2-decimal-places

Parameters:

accurateDecimalPlaces - is number of decimal places that number should have. See note above.

decimalPlaces - is number of decimal places that number needs to be rounded to.

roundType - is type of rounding to perform. See BigDecimal for types of rounding, ex: BigDecimal.ROUND_HALF_UP

round
```
public static double round(double d,

                           int decimalPlaces)
```
Uses BigDecimal to round number to "decimalPlaces" amount of decimal numbers.
By Default, uses BigDecimal.ROUND_HALF_UP.

Parameters:

accurateDecimalPlaces - is number of decimal places that number should have. See note above.

decimalPlaces - number of decimal places to round to
