string - Formatting floats in Objective C -

-

i need format float (catchy title, he?) 2 decimal places, if decimal places have values aren't zero. example:

i have nstextfield named 'answer', after math couple of floats, want assign 'answerfloat' variable 'answer' nstextfield. far i've got:

[answer setstringvalue:[nsstring stringwithformat:@"%.2f", answerfloat]];

but sets 45 45.00. want whole numbers displayed without zeroes, , decimal numbers displayed respective decimal values.

do need run kind of check before giving stringwithformat? or nsstring offer way handle this?

have tried %g format specifier?

nslog([nsstring stringwithformat:@"%g, %g", 45.0, 45.5]);

php - PHPDoc: @return void necessary? -

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...
