I’m having a problem.
I want to round up to the nearest number ending in 7.
The problem is I don’t know the number I’m gonna be rounding. It’s a variable.
For example it could be 2,134.78. I need it to round up to 2,137.
The first thing I thought was to round it to the nearest integer. In this example 2,135.
So the rounded integer we call it Z.
Now, with this integer (Z) I could probably find how much should I add to itself to sum up to 2,137.
Z could be (another example) 1,233. I need to add to Z this time 4 to go to 1,237 (which is the number I really want).
First thoughts was to subtract Z out of Z and then add some amount that gave me some number that with an if statement if it gave me a certain amount I could probably know how much to add to Z to get the number ending in 7.
I know that numbers ending in 0 need to add 7
Numbers ending in 1 need to add 6
Numbers ending in 2 need to add 5, etc.
What I need to know is how much should I add to an unknown number (or already rounded to nearest int) to get to the nearest number ending in 7.
Did you get it?
Thanks!
