flonum

Display and output a number

Description

flonum is a number-box used to display, input, and output floating-point numbers.

Note: The way floating-point numbers are stored on your computer means that not all numbers can be represented. This means that you will often see values such as 2.3 displayed as 2.29999. Clicking in the Float Display Correction checkbox in the Interface pane of the Max Preferences Window will make the Max application round numbers and truncates them at what it guesses is the least significant digit.

Arguments

None.

Messages

bang Sends the currently displayed number out the outlet.
int input [int]
The number received in the inlet is stored and displayed in the number box and sent out the outlet. A float is converted to int by an int number box, and vice versa.
float input [float]
The number received in the inlet is stored and displayed in the number box and sent out the outlet. A float is converted to int by an int number box, and vice versa.
max maximum-value [list]
The word max, followed by a number, sets the maximum value that can be displayed or sent out by the number box. The word max by itself sets the maximum to None (removes a prior maximum value constraint).
min minimum-value [list]
The word min, followed by a number, sets the minimum value that can be displayed or sent out by the number box. The word min by itself sets the minimum to None (removes a prior minimum value constraint).
(mouse) Clicking and dragging up and down on the number box with the mouse (when the patcher window is locked) moves the displayed value up and down, and outputs the new values continuously.
In the float number box, dragging to the left of the decimal point changes the value in increments of 1. Dragging to the right of the decimal point changes the fractional part of the number in increments of 0.01.
When the active patcher window is locked, numbers can be entered into a number box by clicking on it with the mouse and typing in a number on the computer keyboard. Typing the Return or Enter keys on Macintosh or the Enter key on Windows, or clicking outside the number box, sends the number out the outlet.
select The word select will make the number box active so that you can type numbers straight into it (click on any empty space in a locked patcher to deselect it).
set set-input [int]
The word set, followed by a number, sets the stored and displayed value to that number without triggering output.
