ceiling VHDL function

[scs9gp]

Hi I am looking for a VHDL Function that gives the ceiling of a real number.
The input to the function must be real number and the output which is the ceiling of the input must be an integer number.

Alternatively
The ceiling function of the IEEE.real_math package returns a real number as a ceiling of the real input number does anyone have a function to convert real into integer.

Thanks
George
