## `Pref::trailingZeroes` -- trailing zeroes when printing floating point numbers

#### Introduction

`Pref::trailingZeroes` determines, whether trailing zeroes will be appended, when floating point numbers are printed.

#### Call(s)

`Pref::trailingZeroes(value)`
`Pref::trailingZeroes( <NIL>)`

#### Parameters

`value` | - | `TRUE`, `FALSE` or `NIL`

#### Returns

the last defined value

#### Related Functions

`DIGITS`, `Pref::floatFormat`, `print`

#### Details

- If enabled (with argument `TRUE`), after the significant numbers of a floating point number (behind the point) zeroes will be appended until the number of digits reaches the value of `DIGITS`.
- A call of `Pref::trailingZeroes` without arguments will return the current value. The argument `NIL` will reset the default value, which is `FALSE`.

#### Example 1

By default trailing zeroes will not be displayed:

    >> DIGITS:= 10:
       1.4

                                        1.4

Display of trailing zeroes will be enabled:

    >> Pref::trailingZeroes(TRUE):
       1.4

                                    1.400000000
