1.11 + File Name: 15.8.2.15.js
1.12 + ECMA Section: 15.8.2.15 Math.round(x)
1.13 + Description: return the greatest number value that is closest to the
1.14 + argument and is an integer. if two integers are equally
1.15 + close to the argument. then the result is the number value
1.16 + that is closer to Infinity. if the argument is an integer,
1.17 + return the argument.
1.18 + special cases:
1.19 + - if x is NaN return NaN
1.20 + - if x = +0 return +0
1.21 + - if x = -0 return -0
1.22 + - if x = Infinity return Infinity
1.23 + - if x = -Infinity return -Infinity
1.24 + - if 0 < x < 0.5 return 0
1.25 + - if -0.5 <= x < 0 return -0
1.26 + example:
1.27 + Math.round( 3.5 ) == 4
1.28 + Math.round( -3.5 ) == 3
1.29 + also:
1.30 + - Math.round(x) == Math.floor( x + 0.5 )
1.31 + except if x = -0. in that case, Math.round(x) = -0
1.32 +
1.33 + and Math.floor( x+0.5 ) = +0
