So if you're used to thinking in terms of e as the base of natural logarithms, you must do a mental translation when you see an expression such as 1.39 e-47f in Java

所以倘若您习惯将e作为自然对数的基数使用，那么在java中看到象"1.39e-47f"这样的表达式时，请转换您的思维，从程序设计的角度思考它

The expm1 function returns the value of Ex-1, where E is Euler's constant (approximately 2.7183) and x is the number passed to it.

expm1函数的作用是：计算 e（自然对数的底，其数值大约等于2.7183）的指数；它返回了exp 1的值，甚至当number的值接近零也能计算出准确结果。

In this paper,a forward-secure threshold signature scheme based on the Asmuth－Bloom threshold scheme is proposed.Its security is based on the difficulty of solving discrete logarithm in finite field and quadratic residue on some special conditions.

基于Asmuth－Bloom门限方案，设计了一种新的前向安全的门限签名方案，其安全性基于有限域上求解离散对数的困难性和在特定条件下求解二次剩余问题的困难性。

Species-pairs were positive correlation,including 10 species-pairs were higher significant positive correlation and 24 speciespairs were significant positive correlation, and 263 species-pairs were negative correlation, including 8 species-pairs were higher significant negative correlation and 28 species-pairs were significant negative correlation, which were tested by Spearman＇ s rank correlation coefficient.

正负相关比为0.7643，显著种对占总对数的15.05%，群落优势种种间多呈不显著关联。2）按照31个建群种和优势种对环境的适应方式和主导生态因素，它们被划分为2个生态种组：芦苇组和早熟禾组。3）关帝山撂荒地植物群落以退耕还林的先锋物种为主，表明植物群落处于森林植被恢复的初期演替阶段。

Since the base voltage of the output transistor is the log of the absolute value of IIN, the log and antilog terms cancel, so the capacitor becomes a linear integrator with a charging current directly proportional to the absolute value of the input current.
