Help with calculating time

Hello

I have an issue that i'm not familiar with and again equally not knowledgable to do...so i'm looking for the answer.

the minimal increment a time to calculate on a spreadsheet that i'm working on is .25 minutes. If a user work time is 7.16 then his time within the spreadsheet is represented as 7.25.

My question what is the calculation to make sure any number below .25 is rounded up to .25?

Any help appreciated.

I would like to thank all of you!!

Let

represent the time worked in minutes. We want to round

up to the nearest quarter-minute. Thus we're only concerned with the fractional portion of

let's call it

, and let's call the integer portion

Let

be the rounded time. Then

Yes That's exactly what i'm looking for!! I apologize for my late response but yes that's exactly what i'm looking for. I can write out the code for it, but i'm afraid my math skills are greatly inefficient (Thinking)
