WebJan 1, 2024 · Floating-point conversion to integer can be done with a int cast. The caveat is the cast actually truncate it towards zero which may not be desired. C# float f = 2. 9998f ; int num = ( int ) (f); // num is 2 To fix this problem, add 0.5 before casting. C# float f = 2. 9998f ; int num = ( int ) (f + 0. 5f ); // num is 3 now
