JavaScript integer computation how China? Not Int?

Math.round ()

Thanks!

Math.round () is the way the entire numerical approximation rather than take the whole Should [color=red]parseInt[/color] 1, the conversion to take the entire string [html]<script> Alert (parseInt ( "11.9")) "/script> [/html] 2, to take full float [html]<script> Alert (parseInt (11.9)) "/script> [/html]

ParseInt string into cosmetic surgery for the general, if not rounded integer, we should use Math.floor

Myhyli said in a message Please withheld earlier comparison [html] "Script> Alert (parseInt (-11.9)) "/script> [/html] [html] "Script> Alert (Math.floor (-11.9)) "/script> [/html] I think integer say, is to use [color=red]parseInt[/color], there is no other : P

Math.floor () the small 4.8->4 4.2->4 Math.ceil () large 4.8->5 4.2->5 Math.round () rounded 4.8->5 4.2->4 ParseInt (char) char to int number switch

[html] "Script> N = -11.9 A = new Date (). GetTime () For (var i=0; i<100000; i++) parseInt (-.5) //for (Var i=0; i<100000; i++) nn%1 //for (Var i=0; i<100000; i++) -11.9|0 Alert ((new Date (). GetTime ()) -) "/script> [/html]

As expected by bit operation is the fastest : D

TU good bt die. . . Eastern well. . . Thinking. .

-11.9|0 Understand why caput "or" take on the whole operation? ? ?
