WMLScript » Float » Float.int
- Syntax:
- Float.int(value)
- value
- 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.
Returns the integer portion of a floating-point number.
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.
