floating point - Leading zeros for float in Swift -

here float value:

5.3 23.67 0.23 

and want them be

05.30 23.67 00.23 

using string(format: "%.2f", floatvar) can make 2 digit following decimal point cannot add 0 before it.

i've tried string(format: "%04.2f", floatvar) suggest here display same %.2f

is there clean way of doing within swift standard libraries?

try this:

string(format: "%05.2f", floatchar) 

from this documentation: 0 means pad leading zero. 5 minimum width, including dot character.
