Math.Ceiling Method (Double)
Assembly: mscorlib (in mscorlib.dll)
A double-precision floating-point number.
Return ValueThe smallest integer greater than or equal to a. If a is equal to NaN, NegativeInfinity, or PositiveInfinity, that value is returned.
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 a is positive, the presence of any fractional component causes a to be rounded to the next highest integer. If a is negative, the rounding operation causes any fractional component of a to be discarded. The operation of this method differs from the Floor method, which supports rounding toward negative infinity.
