Answer 1

⌊7.5⌋ means "floor of 7.5"

Answer 2

refresh the page if you get weird symbols

Answer 3

anyways, when you take the floor of a number, you round down to the nearest integer

that means 7.5 will floor to 7. This happens no matter how close 7.5 is to 8

Answer 4

if you wanted to floor something like -3.2, you would move onto -4

this is because -4 is below -3

Answer 5

ok thanks @jim_thompson5910 appreciate the info

Answer 6

the ceiling function works in the opposite way

\[\large \lceil 7.5 \rceil = 8\]
\[\large \lceil 7.1 \rceil = 8\]
\[\large \lceil 7.3 \rceil = 8\]
\[\large \lceil -3.2 \rceil = -3\]

you round up to the nearest whole number
