I have the value 25.00 in a float How can I display the value with x number before dot.
Number after dot can be format with "%.xf" (x is number after dot)
But how can i print like this with "%4.2f"
25.00 -> 0025.00
123.12 -> 0123.12

    FYI - Look into `NSNumberFormatter` instead of using a string format. This will give better output based on the user's locale. – rmaddy Jan 09 '16 at 04:56

Use a format string like this: %07.2f where 7 is the total length of the output (including the decimal point) and 2 is the number of digits after the decimal. The 0 causes leading zeros to be used to pad the number (instead of spaces). 

let str1 = NSString(format: "%07.2f", 25.00)  // str1 = "0025.00"
let str2 = NSString(format: "%07.2f", 123.12) // str2 = "0123.12"

  • Should mention that the `0` in the format means that the value will be padded with zeros to fill an remaining space. Without the `0` the extra room will be filled with spaces. – rmaddy Jan 09 '16 at 04:55
