Float.ceil
Float.floor
Float.round
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.
