我需要通过手动计算（常数为 df <- structure(list(Location = c("L1", "L2", "L3", "L1", "L2", "L3"
), Day = c("05/13/2018", "05/13/2018", "05/13/2018", "05/14/2018",
"05/14/2018", "05/14/2018"), `Lab Charge` = c(18, 12, 22,
14, 11, 11), `Elec Charge` = c(19, 14, 16, 20, 14, 14),
`Mach Charge` = c(19, 22, 16, 15, 15, 15)), row.names = c(NA,
-6L), class = c("tbl_df", "tbl", "data.frame"))
df
Location Day Lab Charge Elec Charge Mach Charge
L1 05/13/2018 18 19 19
L2 05/13/2018 12 14 22
L3 05/13/2018 22 16 16
L1 05/14/2018 14 20 15
L2 05/14/2018 11 14 15
L3 05/14/2018 12 14 15
的EPSILON来计算输入数字的平方根。我的代码有什么问题？
(x2 - a) > EPSILON答案 0 :(得分：3)
您的循环正在迭代变量：xadeux，a和epsilon
您在循环内更改的参数是x
这就是循环无限的原因，因为（xadeux-a）> epsilon）始终保持不变
