No, you did not round it right, the number next to the 5 is above five so you need to round up, the answer is 0.706.

Just divide 34 into 24, which goes in 0 times, then put a point down a decimal point and then divide 34 into 240.
This goes in 7 times with 2 left over. Then do 34 divided by 20, as you have now put the remainder (2) over the next zero.
34 divided by 20 is again zero. So the 20 carries over to the next zero making 200. 34 goes into 200 five times with thirty left over. Then you do 34 divided by 30 plus another zero with is 300, the answer is 8. Then like i said before you round up because for numbers 5 or bigger make the decimal place before it round up, otherwise the number stays the same. Giving the answer 0.706.

0 0 .7 0 5 8
__________
2 2 3
4 2 0 0
34 : 2 4. 0 0 0 0

No, but it’s not difficult to write code yourself to do that.

Say the number is stored in X.
:If not(fPart(X/2
:X/2→X

Or if you want it all on one line (takes the same amount of memory, though – 13 bytes):
:X/(1+not(fPart(X/2→X

Edit: Oh hey! Kazuma brought up one of my answers from about a year ago that goes over a mod function workaround. You’d use that if you want to find the remainder of some division.

The edges of three cubes are consecutive odd integers.
If the cubes are stacked on a desk,
the total exposed surface area is 381 cm^2.
Find the lengths of the sides of the cube.
(x – 2), x and (x + 2)
The exposed area of the first cube = 4(x + 2)^2 – x^2
The exposed area of the second cube = 5x^2 – (x – 2)^2 – (x + 2)^2
The exposed area of the top cube = 5 (x – 2)^2
The total exposed surface area:
4(x^2 + 4x + 4) – x^2 + 5x^2 – (x^2 – 4x + 4) – (x^2 + 2x + 4) + 5(x^2 – 4x + 4) = 381
11x^2 – 2x + 28 = 381
11x^2 – 2x – 353 = 0
x = 1/11(1 – 2√971) = -5.5747
x = 1/11(1 + 2√971) = 5.7565
The lengths of the sides of
the cubes are 3.76, 5.76 and 7.76.

Antonella bought some calculators for a total of $240.
She kept one for herself and sold the rest for $300
making a profit of $5 on each calculator.
How many calculators did she buy?
Let x = „number bought“
(selling price) – (cost) = (profit)
(300/(x – 1)) – (240/x) = 5
300x – 240(x – 1) = 5x(x – 1)
300x – 240x + 240 = 5x^2 – 5x
5x^2 – 65x – 240 = 0
x^2 – 13x – 48 = 0
(x – 16)(x + 3) = 0
Antonella bought 16 calculators.

To start out you should know a few things…
If a function is even then f(-x) = f(x)
If a function is odd then f(-x) = -f(x)

You should also know that cos(x) is even; cos(-x) = cos(x)
You should also know that sin(x) is odd; sin(-x) = -sin(x)
The above are basic identities you should have from trig.

First one
f(x) = sec(x) tan(x)

Check f(-x) to see if it’s either even or odd
f(-x) = sec(-x)tan(-x)

You may know whether sec and tan are even or odd, or you may not. However know about cosine and sine so write it in terms of what you know
f(-x) = 1/cos(-x) * sin(-x) /cos(-x)

We know cos(-x) = cos(x)
f(-x) = 1/cos(x) * sin(-x) /cos(x)

And we know sin(-x) = -sin(x)
f(-x) = 1/cos(x) *-sin(x)/cos(x)

Put it back in terms of sec(x) and tan(x)
f(-x) = -sec(x)tan(x)

Well f(-x) is just -f(x) so it’s odd

For
f(x) = 1 -sin(x)
f(-x) = 1-sin(-x)
f(-x) = 1+sin(x)

Well it’s surely not even.. Is it odd?
If it was it would be -(1-sin(x)) or -1+sin(x) and it’s not.

So it’s neither..
