What's the difference between ceil and round

Answer 1

In simple words,

ceil() will always return nearest higher integer.

round() will return nearest higher or lower integer.

Answer 2

Just adding :

round results to less than or equal of 0.5 to 0.0 and greater than 0.5 to 1.0 for any decimal point position...
Where as ceil result both to 1.0

Ex :
round(0.4) =>0.0 ; ceil(0.4) => 1.0
round(0.7) =>1.0 ; ceil(0.7) => 1.0
