go Log1p()
Log1p()方法语法
func Log1p(x float64) float64
go源码对Log1p()方法的介绍：
Log1p returns the natural logarithm of 1 plus its argument x. It is more accurate than Log(1 + x) when x is near zero.
Special cases are:
Log1p(+Inf) = +Inf
Log1p(±0) = ±0
Log1p(-1) = -Inf
Log1p(x < -1) = NaNgolang模块math.Log1p()方法，所求的自然对数值类似于Log(1+x)，但是在求参数x接近0的情况之时，Log1p()方法更加精确。除此之外，Log1p(+Inf) = +Inf；Log1p(±0) = ±0；Log1p(-1) = -Inf；Log1p(x < -1) = NaN；Log1p(NaN) = NaN。
math.Log1p()方法实例代码
func main() {
log1p_v := math.Log1p(0.1)
fmt.Println(log1p_v)
}运行go文件，得到输出：
