# Show Number
|
|
|
|
Show a number on the [LED screen](/device/screen). It will slide left if it has more than one digit.
|
|
|
|
~~~~sig
|
|
basic.showNumber(2, 150)
|
|
~~~~
|
|
|
|
### Parameters
|
|
|
|
* `value` is a [Number](/reference/types/number).
|
|
* `interval` is an optional [Number](/reference/types/number). It means the number of milliseconds before sliding the `value` left by one LED each time. Bigger intervals make the sliding slower.
|
|
|
|
### Examples:
|
|
|
|
To show the number 10:
|
|
|
|
~~~~blocks
|
|
basic.showNumber(10)
|
|
~~~~
|
|
|
|
To show the number stored in a variable:
|
|
|
|
~~~~blocks
|
|
let x = 1
|
|
basic.showNumber(x)
|
|
~~~~
|
|
|
|
### Example: count to 5
|
|
|
|
This example uses a [for](/reference/loops/for) loop to show numbers ``0`` through ``5`` on the screen:
|
|
|
|
~~~~blocks
|
|
for (let i = 0; i < 6; i++) {
|
|
basic.showNumber(i)
|
|
basic.pause(200)
|
|
}
|
|
~~~~
|
|
|
|
