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.
