Example 1: Format Decimal Places in R Using sprintf()
num <- 1.34567 # use sprintf() to format decimal places of num sprintf(num, fmt = '%#.4f') Output: [1] "1.3457"
In the above example, we’ve used the sprintf() function to print the given floating-point number num to 4 decimal places. The 4 decimal places are given by the format .4f.
This means, the function prints only up to 4 places after the dot (decimal places), and f means to print the floating-point number.
Example 2: Format Decimal Places in R Using format()
num <- 1.34567 # format decimal places using format() format(num, digits = 5) # Output: [1] "1.3457"
Here, we have used the format() function to format decimal places of num.
Since we have passed digits = 5 inside format(), the number of digits to be returned along with the number before decimal point is 5.
