What do you mean? Could you specify the rules you use to do that?

for example,

100.251 - 100.253 ~ 100.250
100.254 - 100.256 ~ 100.255
100.257 - 100.259 ~ 100.260

is it what you suppose to have?

.... but for answers there ...like 1+ Math.Floor(x) , and even a long
discussion about why (int)(x + 0.4) is better than (int) ( x+ 0.5) ,
with some sites where you have to "pay" to see the 'certified solution(s)'
!!



Math.Floor( 0.5 + 20*x) / 20.0

to round-to-the-nearest 1/20, not necessary up, and that, for positive
values of x. To round-up-to the next 1/20 (unless it is already an exact
1/20), rather use

Math.Ceiling( 20*x ) / 20.0


It may also be a technical problem about what it really does for x a
floating point number, since technically it makes sense for decimal number,
but for a float...?

Finally, it may not be in agreement with banks policy, which don't
systematically round someInt + 0.5 always up to the someInt+1 (they
would lose money, given the large amount of rounding operations they
perform).

While I agree with the tack you are sailing on, C# round up does not answer
the user's question.
