FUNCTION: Float.ceil
Float.ceil(value)
The Float.ceil function returns the next largest integer (in a
positive direction) for a given floating-point number. If the number is
already an integer, then that same integer value will be returned.
If the browser does not support floating-point arithmetic operations,
then the browser will not recognize the Float Library, nor any
of the member functions. In this case, the Float.ceil function
returns invalid.
The similar Float.floor function returns the next smallest integer.
The mandatory value parameter can be any positive or negative single-precision
floating-point number or any positive or negative integer number (including
zero). The floating-point number must reside on or between the largest
number and the smallest nonzero number supported by the browser. These
boundary values can be determined using the Float.maxFloat and
Float.minFloat functions.
