    round a number to the first 10, 50, 100

    I have a number, for example 0.152 or 1.729 and I want to allow to round to
    the first 0.010 or 0.050 or 0.100

      One approach:

      Use the Decimal data type.

      Multiply by 100, or 20, or 10.

      Round to nearest integer.

      Divide by the number you multipied by.

      But also look for built-in rounding functions.

          still unable to get it..

          what I want is the following:

          0.171 round to 10 is 0.180
          0.264 round to 10 is 0.270
          0.397 round to 10 is 0.400
          1.993 round to 10 is 2.000

          using the same logic I want to round to 50 and 100

              Michael's method rounds to the nearest 10th, 100th, etc. If you want to
              always round up, try this instead (not tested):

              decimal value = 0.171;
              value *= 10;
              value = decimal.Ceiling (value);
              value /= 10;
