Re^2: Trimming of the decimal part.

It should be noted that int always rounds down, while sprintf will flexibly round the proper direction. I didn't notice which way the OP wanted, nor whether the distinction would matter in the particular case. It's a good issue of which to be aware, though.

I know that `int( )` is truncating the fractional part away, i.e. is always rounding down. The OP said: But I do not want the decimal part printed in the above output.. This means truncation to me. Maybe I took it to literal. So far I can remember my last encounter with true rounding in Perl the `sprinf` function is really the best, like you already said. For other rounding functions like `floor()` and `ceil()` the `POSIX` module can be used. Update: Just tested `sprintf("%d")` and it truncates like `int()`. A function which implements "normal" rounding, away from zero from .5 starting is: `sub round ($) { return sprintf("%.0f", shift); }` [download]	[reply] [d/l] [select]
