== The Float Fields ==

{{PrF_UG_TOC_inst}}<div id='prf_ug'>

When an instance is created for a class with a slot of
[[PrF_UG_slots_value_type_float|Value Type Float]],
the entry field corresponding to the slot is a Float entry field,
and takes numbers as values.
These numbers may include a decimal point.
Values of type Float are stored on your system as floating-point values,
and are only as accurate as your system allows.

<ul class='a'>

<li>

<ul>

<li>
[[#remove|removing a value]]

</ul>
</ul>

=== Entering Floating-Point Numbers ===

When entering a Float value for an instance,
you can use decimal point or exponential representation.
You can enter positive and negative values.
For example:

{| summary="floating-point examples"
! Representation
! Description
|-
| 1234.56
| Standard decimal notation.
|-
| 1.23456E3 or 1.2345e3
| Exponential notation;
the example is shorthand for 1.23456 · 103.
Represents 1234.56
|-
| -1234.56
| Negative number.
|-
| 1.23456E-3 or 1.2345e-3
| Exponential notation with a negative exponent,
shorthand for 1.23456 · 10-3.
Represents 0.00123456.
|}

For convenience in typing,
when using exponential notation,
you can enter either e or E.

=== Single Cardinality ===

The entry field corresponding to a slot of value type Float with Cardinality Single can contain a single floating-point number.
It appears as an entry bar:

<div>[[Image:PrF_UG_inst_filled_entry_float.png|instances_filled_entry_float]]</div>

<ul class='a'>
<li>
To set or edit the value,
simply click in the entry field and make your edits.


<li>
To clear the slot,
delete the value in the entry bar.

</ul>

=== Invalid entry in a Float field ===

If you enter text or other invalid information (e.g.,
values less than the
[[PrF_UG_slots_slot_editor#Minimum_optional_|minimum]]
or greater than the
[[PrF_UG_slots_slot_editor#Maximum_optional_|maximum]])
in a Float entry field,
the entered information will be displayed in red and will not saved by the system.
The previous value
(if any)
will be used,
instead.

<div>[[Image:PrF_UG_inst_filled_entry_float_bad.png|instances_filled_entry_float_bad]]</div>

=== Multiple Cardinality ===

An instance with a Float/Multiple slot shows a display list with three buttons.
This field contains a list of floating-point values.
If the at most value is set in the
[[PrF_UG_slots_slot_editor#Cardinality|Cardinality]]
field for the slot,
there is a limit on the number of values you can enter.

<div>[[Image:PrF_UG_inst_filled_entry_float_multiple.png|instances_filled_entry_float_multiple]]</div>

To edit a pre-existing value for a Float/Multiple slot:

<ol class='a'>
<li>
Select the value you want to edit.


<li>
Click the View Value
[[Image:PrF_UG_all_object.view.gif|all_object.view]]
button.
An Edit Float Value dialog box will be displayed.


<li>
Edit the number directly in the dialog box.


<li>
Click OK.

</ol>

To add a value to a Float/Multiple slot:

<ol class='a'>
<li>
Click the Create Value
[[Image:PrF_UG_all_object.add.gif|all_object.add]]
button.
A Create Float Value dialog box will be displayed.


<li>
Enter the number you want in the entry bar.
The number may include a decimal point.


<li>
Click OK.

</ol>

To remove a value from a Float/Multiple slot:

<ol class='a'>
<li>
Select the value(s) you want to remove.
You can select multiple values by holding down the Ctrl (Cmd) key.


<li>
Click the Remove Value
[[Image:PrF_UG_all_object.remove.gif|all_object.remove]]
button.
The selected values will be removed.

</ol>
