Issue ID: 14569 Summary: BigInt is not compatible with the type of immutable (char) and has a problem when converting from a type immutable(char) Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: Phobos Assignee: nob...@puremagic.com Reporter: dennis.m.ritc...@mail.ru In my opinion, this should be corrected: import std.stdio : writeln; import std.conv : to, text; import std.bigint : BigInt; void main() { BigInt twoInThousand = 2.to!BigInt ^^ 1000; string s = twoInThousand.text; BigInt sum1, sum2, sum3, sum4; foreach (e; s) { // sum1 += e.to!BigInt; // Error: template instance // std.conv.to!(BigInt).to!(immutable(char)) error instantiating sum2 += e.to!int; // wrong sum3 += e.to!uint; // wrong sum4 += e.text.to!BigInt; // OK } writeln(sum2); // 15862 // wrong writeln(sum3); // 15862 // wrong writeln(sum4); // 1366 // OK } --
