The **`abs()` function** returns the absolute value of a number. 

Figure 1 shows a mathematical representation of the `abs()` function.

# Syntax
```r
abs(num)
## where num is the number whose absolute value is required
```
## Parameter
The `abs()` function takes a number as a parameter. 

## Return value
The `abs()` function returns the *absolute value* of the number passed as a parameter.  

## Code




#Positive number 
a <- abs(5);
print(paste0("abs(5): ", a))

#negative number 
b <- abs(-5);
print(paste0("abs(-5): ", b))

#zero
c <- abs(0);
print(paste0("abs(0): ", c))
