Find the nearest whole number and whole number+/-0.5 for a given value

6 views (last 30 days)
Hi guys,
I have a simple example. If I have a value:
value = 0.73;
What I want to do is to automatically find what the nearest whole number is +/- 0.5 for a given value. So for example, I want to have something like this:
v0 = 0.73;
v1 = some code; %Tells me 0.5
v2 = some code; %Tells me 1.0
Does this make sense? Here's another example:
v0 = 102.21;
v1 = some code; %Tells me 102.0
v2 = some code; %Tells me 102.5
Thank you!

You want
v2 = ceil(2*v0)/2
v1 = floor(2*v0)/2
The "round to the closest value" is
round(2*v_0)/2

may be you find the following useful:
v0=100*rand
v0_floor=floor(v0)
v0_ceil=ceil(v0)
v5=.5*(v0_floor+v0_ceil)
if v0<v5
v1=v0_floor;v2=v5
else
v1=v5;v2=v0_ceil
end
