#### Digits, VPA, N, Matlab, Mathematica - Doing numerical math

```Hello,

Can someone help me with an issue about digits and vpa command? The
limit of digits in matlab is only 50? For example, I've done the
following test:

>> digits

Digits = 100

>> vpa((1+sqrt(5))/2,100)
ans =

1.618033988749894902525738871190696954727172851562500000000000000000000000000000000000000000000000000

(note the 0's)

Now, using Mathematica i've able to get it:

In:= N[(1+Sqrt)/2,100]

Out=
1.618033988749894848204586834365638117720309179805762862135448622705260462818902449707207204189391137

Question 1) : How can I get the same answer in Matlab as I got in
Mathematica? I saw Matlab working with more than 50 digits only with
certains constants like Pi.

Question 2) : Is there any way to output my math expressions like in
Mathematica, Maple, MathCAD or I must convert it to LaTeX each calc I
need to output? The pretty command is ugly and is pure text.

Thank you all very much for the attention,
Baruch
