FUNCTION: Float.int
Float.int(value)
The Float.int function returns the integer portion of a given floating-point
number. The decimal and all digits to the right of the decimal are simply
discarded. 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.int function returns
invalid.
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.
