"Code note" floating-point number processing and removing the extra 0

One, code.

-(void) viewdidload{    [Super Viewdidload];    Do any additional setup after loading the view.        NSLog (@ "--float-%@-", [self stringdisposewithfloat:9.000899990000]);    } #pragma-mark-functions//floating-point number to process and remove excess 0-(NSString *) Stringdisposewithfloat: (float) floatvalue{nsstring    *str = [ NSString stringwithformat:@ "%f", Floatvalue];    Long len = str.length;    for (int i = 0; i < len; i++)    {        if (![ Str  hassuffix:@ "0"]) break            ;        else            str = [str substringtoindex:[str length]-1];    }    if ([Str hassuffix:@ "."]) Avoid being parsed into 2 like 2.0000.    {        //s.substring (0, len-i-1);        return [str substringtoindex:[str length]-1];    }    else    {        return str;}    }

Two, output.
