The Float.round function rounds a given floating-point number to
the nearest integer value and returns that value.
If the decimal portion of a positive floating-point number lies between
.00000000 and .49999999, the number is rounded down (toward zero, becoming
less positive). Otherwise, a positive floating-point number will be rounded
up (away from zero, becoming more positive).
If the decimal portion of a negative floating-point number lies between
.00000000 and .49999999, the number is rounded up (toward zero, becoming
less negative). Otherwise, a negative floating-point number will be rounded
down (away from zero, becoming more negative).
If the number is already an integer, then that same integer value will
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.round function
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
