How to round decimal value up to nearest 0.05 value?

Question

Is there any way to round up decimal value to its nearest 0.05 value in .Net?

Ex:

7.125 -> 7.15

6.66 -> 6.7

If its now available can anyone

Answer 1

I could not get proper rounding in most of the formulas

This one "rounds" to nearest

float roundFloat(float value, float toNearest) {
            float divVal = (1 / (toNearest == 0 ? 1 : toNearest));
            return ((float)(Math.Round(value * divVal)) / divVal);
        }

Result:

roundFloat(2, 0.125F); -> 2
roundFloat(2.11, 0.125F); -> 2.125
roundFloat(2.22, 0.125F); -> 2.25
roundFloat(2.33, 0.125F); -> 2.375
roundFloat(2.44, 0.125F); -> 2.5
roundFloat(2.549999, 0.125F); -> 2.5
roundFloat(2.659999, 0.125F); -> 2.625
roundFloat(2.769999, 0.125F); -> 2.75
roundFloat(2.879999, 0.125F); -> 2.875
roundFloat(2.989999, 0.125F); -> 3

Example 0.125 nearest rounding

 2.000 
 2.125 
 2.250 
 2.375 
 2.500 
 2.625 
 2.750 
 2.875 
 3.000
