==Definition==
'''INT''' write_float ( <'''INT''' fontID> , <'''INT''' x> , <'''INT''' y> , <'''INT''' alignment> , <'''FLOAT POINTER''' var> )

Writes a [[float|floating point variable]] to the screen, which will be automatically updated when the value of the variable changes. The floating point variable will remain on the screen until deleted with [[delete_text]]().

== Parameters ==
{|
| '''INT''' fontID || - The [[FontID]] of the font to be used for the text.
|-
| '''INT''' x || - The X coordinate of the text.
|-
| '''INT''' y || - The Y coordinate of the text.
|-
| '''INT''' alignment || - The type of [[Alignment modes|alignment]].
|-
| '''FLOAT POINTER''' var || - A [[pointer]] to a [[float|floating point variable]].
|}

== Returns ==
'''INT''' : [[TextID]]
{|
| 0 || - Error. The text could not be obtained or was empty.
|-
| !0 || - The [[TextID]] of the text.
|}

== Notes ==
There is a limit of 511 texts to simultaneously exist on the screen. The program will crash with an error when this number is reached.

The text depth can be changed by adjusting the global variable [[text_z]].

Instead of [[write_float]](), [[write_var]]() can be used for the same purpose, which is a more general function that allows you to write variables of any type to the screen.

== Errors ==
''<If someone knows, please edit!> ''

== Example ==
<pre>
Program test;
Global
Float My_float=3.14159265;

Begin
Write_float(0,320/2,200/2,4,offset My_float);
Loop
Frame;
End
End
</pre>

This will result in something like:<br/>
