Rounding to certain number multiple

[eyadthebest]

hello,

I wan't to ask if Revit have a function that can round a formula output to the nearest  multiplier  of a number such as (26 cm ,52, 78, 104 etc)

the formula is a family parameter,if the output is 27 then it rounds it to 26

and if the output is 62 then it rounds it up to 78 etc...

thanks

round(a / 26) * 26

where "a" is a variable - user input.

The rounding examples are not consistent. 27 to 26 is rounding down, 62 to 78 is rounding up even though 62 is closer to 52 than to 78.

yes sorry i meant like 68 to 78 

as some rounds up and some rounds down to the nearest interval 

thanks
