Question

Which of the following evaluates to the variable x rounded to two decimal places?

A. round(x, 2)
B. round(2, x)
C. round(x), 2
D. round(2), x

Answer 1

A. round(x, 2)

Step-by-step explanation:

It depends on the specific language you're using, but in most language it will follow the syntax round(x, 2).

In the first parameter you enter the value to be rounded (in this case 'x'), and in the second parameter you indicate how many decimals you want to have it rounded to (in this case '2').

Let's suppose we have number 34,54924 as x:

round(x,0) = 35

round(x,1) = 34,5

round(x,2) = 34,55

round(x,3) = 34,549
