WebIn VB.NET, the / operator is defined to return a floating-point result. It converts the variables to double before performing the division. This is not the case in the integer division \ where the division is performed without the remainder if the quotient is a decimal (decimals are ignored). For example if the quotient is 3.x, then x is ignored. 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.
