Rounding to non-standard numbers in MQL4

when trading CFD's which potentially have a minimum increment/tick size of 0.25 in the case of the S&P500, I need to find a way of rounding a number such as a moving average or ATR to the nearest of the smallest increment.

NormalizeDouble(78.2123,0.25) will truncate the 0.25 to the nearest number in this case 0 then round to 78

as will:

MathRound(78.2123)

anyone have any ideas?

cheers

Inserted Code
double d = 78.2123;
double ticksize = 0.25;
d = (int)(d / ticksize + ticksize) * ticksize;
NormalizeDouble(d, 2);
Print(d);

You can also try
Inserted Code
   double a=78.1251;
   double ticksize=0.25;
   a=NormalizeDouble(MathRound(a/ticksize)*ticksize,2);
   Print("a="+DoubleToStr(a,2));
