Can some one tell me how to roud a decimal number into nearest whole number using python. Because 'round()' failed for me. 🐍

Question

By Using PYTHON

Eg. 5.6 i need 6
4. 4 i need 4

Answer 1

The tests are a bit weird.

There were several reports about solutions that shouldn't work but did. I encountered a few myself.

For example here:

Answer 2

In C++ both "ceil()" and "round()" Worked, they pass all 5 tests... How Come ??? 😐😐

Answer 3

In the solution of "Paint costs" in code coaching.. Did you use round(). I tried multiple times and it fails. Can u help me with that plz ??

Answer 4

Ooowh! Thank you for that. I Got this Now. 👍

Answer 5

Got it! I tried math.ceil() ... Thank you!
😐 in java and c++ that round() function works. so is round() used to round up in c++ and java. ?

Answer 6

That's exactly what the round function does.

round(5.6) -> 6
round(4.4) -> 4

Answer 7

It is impossible to be fault check your dot.. maybe you used comma

Answer 8

In paint cost you need to "round up" to the nearest whole number.

Answer 9

Either you can use math.ceil() you can use round() to use round the syntax is
round (float value to be rounded,no of decimal places upto which it would be rounded)

Answer 10

But i will prefer you round over ceil

Answer 11

In C++, you can get ceil from <cmath>. In Java, it's Math.ceil.

Answer 12

In order to round up the value, you have to use round() function
For instance

decimal_no = 343.5567
print(round(decimal_no)
print(round(decimal_no, 2) # 2 means the no. gets rounded to two digits

Here output:
344
343.56

More info:

Like some other suggested ceil() and floor(), let me add some more points. In order to use those functions the math library is used.
ceil(x) - It returns the highest value of x
floor(x) - It returns the lowest value of x

from math import ceil, floor # import math <- This could also be used but use math.func()
dec_no = 454.45343
print(ceil(dec_no))
print(floor(dec_no))

Output:
455
454

Answer 13

You can import math
And then use math.ceil(x)
(Return the ceiling of x, the smallest integer greater than or equal to x.)

Answer 15

U can either use ceil() to round off to the up number eg. 3.666 to 4.0 or use floor() to round off to the lower number eg. 3.66 to 3
