No.  The mask string is passed relatively directly to sprintf, with no
hidden charges or destination fees.  %f gets you the whatever your C
library does by default.

This is one way, but there are more efficient methods:

    FLT = "%.2f"
    print ("abc="+FLT+" def="+FLT) % (3.0,4.5)

Are you trying to do currency?  There are better ways, using the locale
methods.
