rounding up cash

[Mjh35]

i would like to round up or down cash numbers to the nearest .25 so if i put a figure in of £23.21 it would give a value of £23.25 or if i put a value of £23.10 it returns £23.00 if i put a value of £23.89 it would return a value £24.00 so which ever is the closest to .00, .25, .5,.75,.00
