WMLScript » Float » Float.ceil
- Syntax:
- Float.ceil(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.
Rounds a floating-point number up to the next larger integer 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.
