If you're looking for something to print a string formatted to the
correct number of decimal places, but retaining the original number
then consider the following...

'****************************************************** FUNCTION FSINGLE2STR$
' Procedure returns a formatted string variable from a floating point
' (single) variable.  The variable can be a SINGLE defined in a TYPE
' variable.
' CALL: FSINGLE2STR$(float!, format$)
' ARG:  float!  - floating point variable to be converted to string
'       format$ - format required using PRINT USING format
' RET:  string
' COMP: MS Basic 7.1
' REV:  92-02-01
FUNCTION FSINGLE2STR$ (float!, format$)

  filenum% = FREEFILE
  OPEN "\DEV\NUL" FOR RANDOM AS #filenum% LEN = 15
  FIELD #filenum%, 15 AS temp$
  LSET temp$ = ""
  PRINT #filenum%, USING format$; float!;
  FSINGLE2STR$ = TRIM$(temp$)
  CLOSE #filenum%


and TRIM$() is just something like RTRIM$(LTRIM$(a$))
