Betreff: st: float function question

.

Why does the float function not work like this? I feel silly.

clear
input float x
0.00
0.01
0.03
0.10
0.30
1.00
end
generate str4 x_str = ""
replace x_str = "0.00" if float(x) == 0.0
replace x_str = "0.01" if float(x) == 0.01
replace x_str = "0.03" if float(x) == 0.03
replace x_str = "0.10" if float(x) == 0.1
replace x_str = "0.30" if float(x) == 0.3
replace x_str = "1.00" if float(x) == 1.0
list, clean

which gave

. list, clean

          x   x_str
   1.     0    0.00
   2.   .01
   3.   .03
   4.    .1
   5.    .3
