simp_mode - toggle rational simplification

### Calling Sequence

  `mod=simp_mode()`
  `simp_mode(mod)`

### Parameters

- `mod` : a boolean

### Description

rational simplification is called after nearly each operations on rationals. It is possible to toggle simplification on or off using `simp_mode` function.

`simp_mod(%t)` set rational simplification mode on

`simp_mod(%f)` set rational simplification mode off

`mod=simp_mod()` returns in mod the current rational simplification mode

### Examples

    s=poly(0,'s');
    mod=simp_mode()
    simp_mode(%f);hns=s/s
    simp_mode(%t);hns=s/s
    simp_mode(mod);
