## Has evalf(...,n) been deprecated...

Maple

Both uses of evalf

```evalf(Pi, 20);
evalf[20](Pi);```

work, but only the latter is documented. Is there a reason behind (maybe historical)? Any reason not to use evalf(...,n) any more? I am also reluctant to update old worksheets if there is no need for the indexed version.

## Lists and `/`: Why is does the output de...

Maple

Only for my understanding. In the following I need to use expand to apply division to list elements when the divisor is a name:

 (1)

 (2)

 (3)

Does in this case automatic simplification make a difference between numbers and names? (Probably this is explained somewhere.)

## What is substituted here...

Maple

I cannot figure out which operand(?) is substituded here

```subs(1 = 2, a*b);
2  2
a  b
```

Same for

```subs(1 = 3, a + b);
3 a + 3 b

```

but

```subs(1 = 2, a/b);
2
a
--
b

subs(1 = 3, a - b);
3 a - b

```

Is this by design?

## SolveTools:-DisplaySolutions: some quest...

Maple

I very welcome this new feature but here I am stuck

 Originally _Z1, renamed _Z1~:   is assumed to be: integer

 (1)

Questions:
Q1: How to get also the uneven multiples of Pi?
Q2: Why is zero not excluded?
Q3: How to get the desirable output

## Reply to posts slow and sometimes not wo...

MaplePrimes

For the past days I observe that reply to posts stucks at the progess bar

(using a firefox browser). I am wondering whether that is only on my installation. Loading pages is not slow as reported here. I have a suspicion that this happens after having previewed a reply before submission. I observe also sometimes a yellow background of the preview and sometimes a blue background.

I try to submit now with blue backgound
