ln=floor(WIN_sz/2)

what does this mean?

Answer 1

[Birdman]

In case WIN_sz variable is odd, it is rounded to the nearest smallest integer by floor function.

[Roger Stafford]

It would be more accurate to say: "The quantity WIN_sz/2 is set to the nearest integer at or below its value and placed in 'ln' ."

[Komal Gaikwad]

thnx,but 'ln' is just a variable correct??

[Birdman]

Yes.

[Komal Gaikwad]

but in the code it is not declared anywhere,that is why i am confused
