WMLScript » Float » Float.floor

Syntax:
Float.floor(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 down to the next smaller integer value.

The Float.floor function returns the next smallest integer (in a negative 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.floor function returns invalid.

The similar Float.ceil function returns the next largest integer.
