# Ceiling for numbers with unit

## Ceiling for numbers with unit

(OP)
Hi,
How Ceiling is found for numbers associated with units using Mathcad? For example:
Ceil (48.659 in)

There is a way (floor also): I shall look it up (have to find correct sheets) and I will advise.

### RE: Ceiling for numbers with unit

Mathcad converts EVERYTHING to its native units, which is SI. Therefore, even if a function allows for units, you should probably do something like:

ceil(dimension/inch)*inch to preserve the dimensions desired

My MathCAD 2000 (best ever version) came on a disc and with a 700 page printed manual.

It (the manual)says;

floor(x) Greatest integer <= x (x real)

ceil (x) same

It does work..

However, see attachment for use with units.

Remark: I am not sure if Mathcad 2000 already provided the built-in fuction "Ceil" (note the capital C).
If its available in your version you can use it like "Ceil(18.2 mm, mm)=...mm"
If not you may define your own: Ceil(a,b):=ceil(a/b)*b

I have checked the manual; and it says ceil (lower case)
and it does work in that format. MathCAD 200 does have ceil and floor
as built in functions.

I hope this time the file is attached.
