But the connection to the "-" sign is simply not there. Your code with a
positive large number causes the exact same effects:
*************
clear
set obs 1
gen double x = 123456789123456
tostring x, gen(strx)
tostring x, gen(strx) format(%17.0g)
*************

There is no problem with negative signs. Is var_1 a large number? Compare:
clear
set obs 1
gen x = -100
tostring x, gen(strx)
clear
set obs 1
gen double x = -123456789123456
tostring x, gen(strx)
tostring x, gen(strx) format(%17.0g)
If you -set trace on- on the -tostring- that fails, you will see it
appears to default to %12.0g format - which is too small in this case:
- else {
- local fmt "%12.0g"
- local format `", "%12.0g""'
- }
