Public Shared Function Ceiling (x As Single) As Single
Parameters
- x
- Single
A single-precision floating-point number.
Returns
The smallest integral value that is greater than or equal to x
. If x
is equal to NaN, NegativeInfinity, or PositiveInfinity, that value is returned. Note that this method returns a Single instead of an integral type.
Remarks
The behavior of this method follows IEEE Standard 754, section 4. This kind of rounding is sometimes called rounding toward positive infinity. In other words, if x
is positive, the presence of any fractional component causes x
to be rounded to the next highest integer. If x
is negative, the rounding operation causes any fractional component of x
to be discarded. The operation of this method differs from the Floor(Single) method, which supports rounding toward negative infinity.
