You want to get fractional<\/em> part and truncate<\/em> it up to two digits<\/em>. If values are positive<\/em> and small<\/em> you can implement it like this:<\/p>\n

 private static double Solution(double value) {\n    return (long)((value - (long)value) * 100) \/ 100.0;\n }\n<\/code><\/pre>\n
Test:<\/p>\n
 double[] test = new double[] {\n   0.433432,\n   0.672919,\n   3.826342,\n   6.783643, };\n\n var result = test\n   .Select(item => $\"{item} -> {Solution(item)}\")\n   .ToArray();\n\n Console.Write(string.Join(Environment.NewLine, result));\n<\/code><\/pre>\n
Outcome:<\/p>\n
 0.433432 -> 0.43\n 0.672919 -> 0.67\n 3.826342 -> 0.82\n 6.783643 -> 0.78\n<\/code><\/pre>\n
Edit:<\/strong> What’s going on in the Solution<\/code> method:<\/p>\n
