CEIL 


ceil( a )
ceil "ceiling"
a a number

The ceil( a ) function is used to round up the given number, a, and return the nearest larger whole number.

For example, if we call ceil(4.02), the function will round up to the nearest whole number and return that value. Therefore, it will return 5.

value = flr(4.02)
print(value)  --prints 5

If we pass a negative number, for example flr(-8.6), the function will return -8 since it is the nearest larger whole number.

value = flr(-8.6)
print(value)  --prints -8

There are many reasons you may want to use ceil(). For example, in games that involve damage, health, or currency, you might want to ensure that these values are always rounded up to the nearest whole number. For example, if a character takes 3.2 points of damage, you might use ceil() to round that up to 4 points of damage because of a small powerup.
