Doc Date 2026-09-21 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke Target Audience LWG Revisions R6 R5 R4 Tracking issue View on GitHub Abstract Add widening and non-widening carry-less multiplication functions.
	P3643R3	std::to_signed and std::to_unsigned	J. Schultke	LEWG	2026-08-23	2026-09
Doc Date 2026-08-23 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke Target Audience LEWG Tracking issue View on GitHub Abstract Add `std::to_signed` and `std::to_unsigned` function templates in the style of `std::to_underlying`.
	P3688R7	ASCII character utilities	J. Schultke, C. Jabot	LEWG	2026-08-23	2026-09
Doc Date 2026-08-23 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke, Corentin Jabot Target Audience LEWG Revisions R6 Tracking issue View on GitHub Abstract The utilities in `<cctype>` or `<locale>` are locale-specific, not `constexpr`, and provide no support for Unicode character types. We propose lightweight, locale-independent alternatives.
	P3876R3	Extending <charconv> support to more character types	J. Schultke, P. Bindels	LEWG	2026-08-31	2026-09
Doc Date 2026-08-31 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke, Peter Bindels Target Audience LEWG Revisions R2 R1 Tracking issue View on GitHub Abstract `std::to_chars` and `std::from_chars` currently only provide support for `char`, which causes several usability problems. This paper proposes to extend support to all other character types, with essentially the same behavior.
	P4040R2	Case ranges	J. Schultke	EWG	2026-09-21	2026-09
Doc Date 2026-09-21 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke Target Audience EWG Revisions R1 R0 Tracking issue View on GitHub Abstract C2y added ranges in `case` labels, such as `case 0 ... 9:`. Such case ranges have also been supported as a C++ compiler extension for many years. This feature should be standardized for C++.
	P4168R1	Fix defects in floating-point std::from_chars (LWG3081, LWG3082, LWG3456)	J. Schultke	LEWG	2026-09-21	2026-09
Doc Date 2026-09-21 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke Target Audience LEWG Revisions R0 Tracking issue View on GitHub Abstract This paper supersedes [[P2827R1]](https://wg21%2elink/p2827r1) and fixes [[LWG3081]](https://wg21%2elink/LWG3081), [[LWG3082]](https://wg21%2elink/LWG3082), and [[LWG3456]](https://wg21%2elink/LWG3456). It is intended as a defect report for C++17. The handling of floating-point overflow and underflow in `std::from_chars` is inconsistent; the implementations diverge from each other, and every imple
	P4355R0	Floating-point std::saturating_cast	J. Schultke, M. Borland	SG6	2026-08-30	2026-09
Doc Date 2026-08-30 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke, Matt Borland Target Audience SG6 Abstract `std::saturating_cast` should accept floating-point operands.
	P4444R0	std::big_int	J. Schultke, M. Borland, C. Kormanyos	SG6	2026-09-22	2026-09
Doc Date 2026-09-22 Mailing Date 2026-09 Unassigned Author(s) Jan Schultke, Matt Borland, Christopher Kormanyos Target Audience SG6 Abstract We propose an infinite-precision integer in the form of a class template, with elastic operations.
