ECMA Section: 15.8.2.6 Math.ceil(x)
|
|
Description: return the smallest number value that is not less than the
|
|
argument and is equal to a mathematical integer. if the
|
|
number is already an integer, return the number itself.
|
|
special cases:
|
|
- if x is NaN return NaN
|
|
- if x = +0 return +0
|
|
- if x = 0 return -0
|
|
- if x = Infinity return Infinity
|
|
- if x = -Infinity return -Infinity
|
|
- if ( -1 < x < 0 ) return -0
|
|
also:
|
|
- the value of Math.ceil(x) == -Math.ceil(-x)
