linear progression

[Pan_Forex]

Hello guys, do you have any idea how to easily add a fixed increment? The only thing I can think of is the if function, but I have several thousand rows and would prefer to streamline it 🙂 Simple data:

x	y
1255	1
2545	0,99
3555	0,98
4787	0,97
6222	0,95
6565	0,95
8855	0,93
9001	0,91
9655	0,91

I would like the function, after x increases by 1000, to subtract 0.01 from y. This can be as a new column or function, of your choice.

hi @Pan_Forex 

from 4787 to 6222, from 8855 to 9001, why subtract 0.01 twice? 

[Pan_Forex]

Because the range is between 0-1000, 1001-2000, in the second example there is an error. let's make it simple. For numbers < 1000-1, between 1001-2000=0,99, between 2001-3000=0,98 and so on

hi @Pan_Forex 

then try this:

y = 1- TRUNC( [x]/1000)*0.01

please consider @ someone, if you seek further suggestions.
