`calc`

(I believe from package `apcalc`

) does the same as `bc`

, but does not round. It displays similarly to `bc`

, but unlike `bc`

, it understands scientific notation. Example:

```
> calc
C-style arbitrary precision calculator (version 2.12.3.3)
Calc is open software. For license details type: help copyright

; b=a/7

~0.00000000000000000033
; c*1e10
~0.00000000334285714286
;
```

Compare with `bc`

:

```
> bc -l
bc 1.06.95

A little search turns up lots of results, not all of which are relevant, but I am sure that a few trials will get you exactly what you want (wcalc, for instance):
