The **`ceiling()` function** returns the smallest integer that is greater than or equal to the number whose ceiling needs to be calculated. 

Figure 1 shows the mathematical representation of the `ceiling()` function and the corresponding expression in R.

# Syntax
```r
ceiling(number)
```
# Parameter
This function requires a number to round up as a parameter.

# Return value
`ceiling()` returns the smallest integer that is greater than or equal to the number sent as a parameter.

# Example


#Positive number
a <- ceiling(10);
print(paste0("ceiling(10): ", a))

b <- ceiling(5.3);
print(paste0("ceiling(5.3): ", b))

#negative number 
c <- ceiling(-10);
print(paste0("ceiling(-10): ", c))

d <- ceiling(-5.3);
print(paste0("ceiling(-5.3): ", d))
