在Stata中,可以使用gen命令结合类型转换函数来生成新的float类型变量: stata gen float new_variable = real(variable_name) 这里,real()函数用于将字符型或数值型变量转换为数值型(默认是double类型),但由于我们将其赋值给了一个float类型的变量,所以结果会被自动转换为float类型。 如果你想要直接修改原变量的类型...

初学者总是容易将destring和encode混淆,其实两者的用途是有区别的: destring: Convert string variables to numeric variables and vice versa. encode: Encode string into numeric and vice versa. encode主要用于将数据进行编码、分组,将连续性变量转换成分组变量。 它可以和另外一组命令一起记忆:encode,decode,recode...
floatis a storage format used by Stata, not a computation format. When you have a number stored as afloatand you make a calculation, such as . gen newvar = sqrt(oldvar)/sqrt(2) oldvaris retrieved and is promoted to adouble. The entire computation is then made in double precision, and...
1、float x=1.23;你这样不能编译通过要在后面加f 2\从float到double的转换是宽转换，所以可以直接 float x = 1.23F;double z = x;Console.WriteLine(z.ToString(，以上就是我的回答。
