In C, the printf() statement allows the precision lengths to be supplied in the parameter list.
printf("%*.*f", 7, 3, floatValue);
where the asterisks are replaced with first and second values, respectively.
I am looking for an equivalent in Android/Java; String.format() throws an exception.
EDIT: Thanks, @Tenner; it indeed works.
I use
int places = 7;
int decimals = 3;
String.format("%" + places + "." + decimals + "f", floatValue);
A little ugly (and string concatenation makes it not perform well), but it works.
