Rounding formula

I think there’s a typo in your original example. If by

round up by 5 or round down by 5

you mean round to the nearest multiple of 5, where 4556 would round to 4555, 2333 to 2335, and 2332 to 2330, the formula you want is

ROUND(number*2,-1)/2

To incorporate that into your current formula, just replace 'number' with your formula:

ROUND((({Original Price AED} * (100 - Discount)) / 100)*2,-1)/2

I can see that it works, but I don’t quite understand how it works so I’m having trouble modifying this formula to round to a multiple of 15. Is this possible? I’m pulling the minute from a date_time field and need to round to the nearest quarter hour.

Thanks,
Jamie

Try

ROUND(nbr*.67,-1)/.67

That seems to work, but play with it a bit to make sure.

Note: Anything 52.5 minutes or longer is rounded up to 60 minutes — which you probably don’t want. Here are two variations:

If nbr is number of minutes, possibly > 60

IF(
    ROUND(ROUND(MOD(nbr,60)*.67,-1)/.67,0)=60,
    INT(nbr/60)+1&':00',
    INT(nbr/60)&':'&ROUND(ROUND(MOD(nbr,60)*.67,-1)/.67,0)
    )

If you’ve already split a time field into {hr} (hours) and {min} (minutes)

IF(
    ROUND(ROUND(min*.67,-1)/.67,0)=60,
    hr+1&':00',
    hr&':'&ROUND(ROUND(min*.67,-1)/.67,0)
    )
