this academic purpose. i noticed integral literals, can declare 18446744073709551615 2^64-1 or ulong.maxvalue . defining greater value produces compile-time error. and floating-point literals, can declare them integral part 999...999 ( 9 repeated 308 times). declaring integral part more digits again produces compile-time error. 1 thing interests me compiler seems allow specify fractional part unlimited number of digits. practically, unlimited number of digits fractional part not make sense. questions: is there constant representing max number of digits internally defined c# compiler fractional part of floating-point number? if such constant exists, why not c# compiler throw compile-time error when users specify fractional parts beyond limit? minimal working example 1 namespace floatingpoint { class program { static void main(string[] args) { const ulong @ulong = 18446744073709551615; const double @double = 99999999
