michael@0 8 File Name: 15.8.2.15.js
michael@0 9 ECMA Section: 15.8.2.15 Math.round(x)
michael@0 10 Description: return the greatest number value that is closest to the
michael@0 11 argument and is an integer. if two integers are equally
michael@0 12 close to the argument. then the result is the number value
michael@0 13 that is closer to Infinity. if the argument is an integer,
michael@0 14 return the argument.
michael@0 15 special cases:
michael@0 16 - if x is NaN return NaN
michael@0 17 - if x = +0 return +0
michael@0 18 - if x = -0 return -0
michael@0 19 - if x = Infinity return Infinity
michael@0 20 - if x = -Infinity return -Infinity
michael@0 21 - if 0 < x < 0.5 return 0
michael@0 22 - if -0.5 <= x < 0 return -0
michael@0 23 example:
michael@0 24 Math.round( 3.5 ) == 4
michael@0 25 Math.round( -3.5 ) == 3
michael@0 26 also:
michael@0 27 - Math.round(x) == Math.floor( x + 0.5 )
michael@0 28 except if x = -0. in that case, Math.round(x) = -0
michael@0 29
michael@0 30 and Math.floor( x+0.5 ) = +0
