Maple

The round(x) statement rounds x to the nearest integer but if x has unirs it appears not to work. Known bug?

## How to use units like km, m, cm...

Maple

Please tell me where I go wrong

And I have not even tried lamda in nanometers

Since theata is small I repalce sin(theta) by theta because, with units, sin did not compute

Anyone know a good reference (book/website) explaing Maple units?

Many thanks

## Symbolic evaluation required...

Maple

From the screenshot we see that Maple has correctly replaced a in the defintion of s. But it has not incorported v[B]. I was a SMath (free from internet) user and this was a simple operation.

Thanks for any advice.

## Assigning 3 values and numeric formattin...

Maple

Q1: In place of three statments like >a:=3: b:=4; c:=5, I have found from an example in this forum that one can use >(a,b,c):=(3,4,5). And I find this useful in some applications. Anyone know what version of Maple introduced this? I can find not referneces in the Maple books I have

Q2: Maple someimes gives 'naked' decimals when I use Numeric formatting. Any way of avoiding this. I would  like 0.25 not .25

Many thanks
