Your comparison is flawed. Take your original playground code (the one with just %0.3f) and change the "f" to "g" without removing the "0.3" and run it again. You will see the same rounding behavior as with "f". The documentation says: The default precision ... for %g ... is the smallest number of digits necessary to identify the value uniquely. So without explicitly specifying the precision, %g will print as many digits as necessary (i.e. enough precision is used to prevent rounding). What representation, using only the precision specified, most closely represents the value being formatted? That is how you should think of the floating point formatting behavior, rather than thinking of it as rounding. ...Marvin -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
