I am building an Application based on a excel sheet, at a certain point the sheet uses
=ROUNDUP(701.25;-1) which is returned as 710… how do we do this in C#
I tried Math.Round that returns 701, If I try to use Math.Round() with -1 then i get this
Rounding digits must be between 0 and 15, inclusive.
Please help me out here.
Try this (you’ll need to cast the return value to int
if necessary):
public static double RoundUp(double value, int digits)
{
double pow = Math.Pow(10, digits);
return Math.Ceiling(value * pow) / pow;
}
This should give you the functionality defined here:

Answer:
use the below two methods.Which may help you
int RoundUp(int toRound)
{
return (10 - toRound % 10) + toRound;
}
int RoundDown(int toRound)
{
return toRound - toRound % 10;
}
