I have a problem with the RoundTo function ()

otherwise it rounds even or odd numbers

if I have RoundTo (number, 0) where number = 46.5 then the result is 46 and if I have RoundTo (number, 0) where number = 45.5 then the result is also 46 search for a function that every time the decimal is 0.5 the result rounded up.

the ceil function is not good because it rounds numbers to integers and I need to round numbers also after a comma.

My number 46.5 is exactly 46.5 because I tested it by giving it directly to the function and the result is the same.
