XMath.rool介绍

[英]Returns the next or previous representable number. If amount is equals to 0, then this method returns the value unchanged. Otherwise, The operation performed depends on the specified type:

• If the type is Double, then this method is equivalent to invoking #previous(double) if amount is equals to -1, or invoking #next(double) if amount is equals to +1. If amount is smaller than -1 or greater than +1, then this method invokes #previous(double) or #next(double) in a loop for abs(amount) times.
• If the type is Float, then this method is equivalent to invoking #previous(float) if amount is equals to -1, or invoking #next(float) if amount is equals to +1. If amount is smaller than -1 or greater than +1, then this method invokes #previous(float) or #next(float) in a loop for abs(amount) times.
• If the type is an #isInteger, then invoking this method is equivalent to computing value + amount.
  [中]返回下一个或上一个可表示的数字。如果amount等于0，则此方法返回的值不变。否则，执行的操作取决于指定的类型：
  *如果类型是Double，那么这个方法相当于在amount等于-1时调用#previous（Double），或者在amount等于+1时调用#next（Double）。如果amount小于-1或大于+1，则此方法在循环中调用#previous（double）或#next（double）以获得abs（amount）次数。
  *如果类型为Float，则此方法相当于在amount等于-1时调用#previous（Float），或者在amount等于+1时调用#next（Float）。如果amount小于-1或大于+1，则此方法调用循环中的#previous（float）或#next（float）进行abs（amount）次数。
  *如果类型是#isInteger，那么调用此方法相当于计算value+amount。
