CEIL  CEIL Ceiling Function


Usage
 
 Computes the ceiling of an n-dimensional array elementwise.  The
 ceiling of a number is defined as the smallest integer that is
 larger than or equal to that number. The general syntax for its use
 is
 
    y = ceil(x)
 
 where x is a multidimensional array of numerical type.  The ceil 
 function preserves the type of the argument.  So integer arguments 
 are not modified, and float arrays return float arrays as 
 outputs, and similarly for double arrays.  The ceil function 
 is not defined for complex or dcomplex types.
