def pure const autodiff floor(quantity: number): number
Returns the entered quantity rounded down to the nearest integer.
Example
show table "" with
floor(-1.7)
floor(-0.5)
floor(0.2)
floor(1.9)
This outputs the following table:
floor(-1.7)
floor(-0.5)
floor(0.2)
floor(1.9)
-2
-1
0
1
Remarks
When used inside an Autodiff block, the gradient associated to floor() is 1, instead of 0, as the mathematical definition would suggest. The purpose of this irregular behavior is to facilate the design of discrete policies.
