However, each thread also has an integer @dfn{nice} value that determines how ``nice'' the thread should be to other threads. A @var{nice} of zero does not affect thread priority. A -positive @var{nice}, to the maximum of 20, increases the numeric -priority of a thread, decreasing its effective priority, and causes it -to give up some CPU time it would otherwise receive. On the other hand, -a negative @var{nice}, to the minimum of -20, tends to take away CPU -time from other threads. +positive @var{nice}, to the maximum of 20, decreases the priority of a +thread and causes it to give up some CPU time it would otherwise receive. +On the other hand, a negative @var{nice}, to the minimum of -20, tends +to take away CPU time from other threads. The initial thread starts with a @var{nice} value of zero. Other threads start with a @var{nice} value inherited from their parent
