C# int division round up
WebFeb 22, 2024 · The Int and Trunc functions round a number to an integer (whole number without a decimal): Int rounds down to the nearest integer. Trunc truncates the number to just the integer portion by removing any decimal portion. The difference between Int and Trunc is in the handling of negative numbers. WebJan 28, 2013 · Division of Int32.MinValue by -1 results in an exception. If the divisor and dividend have the same sign then the result is zero or positive. If the divisor and dividend have opposite signs then the result is zero or negative. If the division is inexact then the quotient is rounded up.

WebRound (Double, Int32, MidpointRounding) Rounds a double-precision floating-point value to a specified number of fractional digits using the specified rounding convention. C# public static double Round (double value, int digits, MidpointRounding mode); Parameters value Double A double-precision floating-point number to be rounded. digits Int32 WebYou see "rounding down" because the truncation happens before reaching Math.Ceiling. When you do this (this.TotalRecordCount / this.PageSize) It is an integer division, and its result is a truncated int; it is too late to cast it to decimal. To fix this problem, cast before the division: Math.Ceiling(((decimal)this.TotalRecordCount / this ...
WebJun 15, 2010 · If you wanted to write this just using integers in a relatively succinct way, then you can write this: var res = a / b - (a % b < 0 ? 1 : 0); This probably compiles to quite a few instructions, but it may still be faster than using floating-points.
