Gompertz 常数 δ = −e·Ei(−1) = e·E₁(1) ≈ 0.596347362323194，出自 Gompertz 增长曲线（肿瘤生长、人口老龄化、产品渗透率的标准模型）的归一化分析，也是「随机斜率」类极值问题里 −e·Ei(−1) 的常客。
它出现在 Graham–Knuth–Patashnik《具体数学》的赠礼问题与 Ramanujan 的 Q 函数讨论中：对随机排列的极长递增子序列、随机映射的峰值分析，δ 都是那个收尾常数。
参考值
δ = 0.596347362323194（e·E₁(1)），1 − δ = 0.403652637676806
E₁(1) = 0.219383934395585，ln δ = −0.517180417072488
