# SMath Problem

## SMath Problem

(OP)
Any idea of why this error message comes up? The answer should be about 600 in^4. The last yb1 should be yb2.

### RE: SMath Problem

1.58e8 + 87696568 = 2.45696568e8

That's above the limit for a signed 32-bit integer.

I don't know if that's important for this case, since SMath shouldn't be using signed 32-bit integers for what you show. Unless somewhere internally it's using them for the conversions between in^4 and mm^4.

Does SMath give you any control or visibility about the number types that it's using?

### RE: SMath Problem

(OP)
Thanks Mint... that could be the problem... drop the metric to m in lieu of mm... I'll try it.

### RE: SMath Problem

(OP)
It doesn't help... It's storing some huge numbers internally for what ever reason... dunno why... I removed all the metric I values... and I get the same message.

### RE: SMath Problem

(OP)
As I noted above, the numbers SMath is using, I assume internally, are extremely large. I don't know if it's possible to set a 'switch' of some sort. I couldn't find a 64 bit Windows version. It's a problem that's popped up a couple of times of late. I'll try reinstalling the program... see if that helps.

### RE: SMath Problem

I would copy everything into another sheet, first.

There's nothing that I see in what you showed that should be problematic. Smath's largest number is around 10^308, so it's unlikely that anything you do in a structural calculation for something on Earth could exceed that.

### RE: SMath Problem

(OP)
Thanks IRS... I'll try that first. It is problematic, and only popped up a couple of times of late... never before...

Didn't work... I'll try reinstalling...

### RE: SMath Problem

(OP)
I broke the value up because it originally worked without the error... treating the total value... as a work around, I'll enter the value of the summation.

Oh, Oh, the number is different... something really strange... It's OK, I changed the beam size to a W16...

### RE: SMath Problem

(OP)
Even more perplexing... I'll see if I save it as a different file name and see if it works... bug of some kind. Current rendition... I use yellow boxes for adding data...

### RE: SMath Problem

(OP)
There is a transformation of some type with eng-tips... saving it as a different file doesn't work to fix it. I'll have to use the work around and hope it works.

### RE: SMath Problem

Some sort of subtle change in the file, causing a numerical change somewhere; some sort of "butterfly effect".

The display of the actual calculation is interesting, but a bit perturbing, since the numerals shown appear with way more precision than necessary, suggesting some sort of issue with truncation, but nothing looks otherwise amiss.

As long as the unassigned variable works... and can be entered 'by hand'.
