LichessNET Sbox Edition
Released
LichessNET API Wrapper which features a board integration API.
Extensions/LongExtensions.cs
Extension methods for long integers. Provides ToSIPrefix which formats a long into a compact string using SI-like thousand-based prefixes (k, M, G, T, P).
🐞 For long.MinValue, Math.Abs overflows leading to NaN then exponent 0, so the method returns a no-prefix value with a trailing space instead of a scaled SI string.
