getMillisFromServerTicks

public static long getMillisFromServerTicks(long serverTicks)

getServerTicksFromMillis

public static long getServerTicksFromMillis(long millis)

roundToX

public static double roundToX(double input,
 double step)

This method rounds up the input to the desired accuracy. The accuracy value specifies the step sizes between which rounding takes place.

• The value is always rounded to the nearest multiple of step.
• Ties (values exactly halfway between two multiples) are always rounded up, following the behavior of Math.round(double).
• Smaller values of step result in finer rounding granularity.

Examples:

• step = 1.0 => 0.0; 1.0
• step = 0.5 => 0.0; 0.5; 1.0
• step = 0.25 => 0.0; 0.25; 0.5; 0.75; 1.0
• step = 0.1 => 0.0; 0.1; ... 0.9; 1.0
• step = 0.05 => 0.0; 0.05; ... 0.95; 1.0

Parameters:

input - (double) the target value for the rounding

step - (double) rounding accuracy

Returns:

(double) the rounded value

isBetween

public static boolean isBetween(double value,
 double limitA,
 double limitB,
 boolean inclusiveLimitValues)

This method checks whether a specific value is within a range of values. Two limit values are used as interval limits, whose order (MIN, MAX) is irrelevant. The limit is included ("Closed Interval"), if 'inclusiveLimitValues' is 'true'. Otherwise, the limit is exclusive ("Open Interval").

Parameters:

value - (Double) the target value for the check

limitA - (Double) the first interval limit

limitB - (Double) the second interval limit

inclusiveLimitValues - (Boolean) 'true', if the interval limits are included in the range

Returns:

(Boolean) 'true', if the target values is a part of the specified interval
