Using string() on double values without automatic rounding?

Hello,
When i use string() with double values, the number is converted to a string where the number is rounded to four decimals, even when there are more decimals in the original double value. Image:
I am currently writing a conversion script where i need the extra decimals. Is it possible to disable this automatic rounding?
Thank you.

There are no more decimals in the original double value. A double value can only have 15 digits of precision.

Rather than slow NUM2STR and then STRING, for a scalar the simpler and more efficient approach is to just call SPRINTF:
sprintf("%.9f",123.123123123)
For non-scalar values use COMPOSE:
