 Ah,
 	I think I have been somewhat 'economical' with the details of this.
 Am porting (n)awk to windows using Microsoft Vis C++ 2022.
 The printf man page says -
 
 a 	Floating-point 	Signed hexadecimal double-precision floating-point
 value that has the form 
 [-]0xh.hhhhp[+|-]dd, where h.hhhh are the hex digits (using lower case
 letters) of the mantissa, and dd are one or more digits for the exponent.
 The precision specifies the number of digits after the point.
 
 Default precision is 13. If precision is 0, no decimal point is printed
 unless the # flag is used.
                                 ^^^^
                     This would seem to be a lie
 But anyway ...
 
 Close this if feel there is nothing to do
 
 Trevor

  Weird. I ran your program and I get:
  
  [10:44am] 1822>./a.out
  xbuf:0x1.5p+5:   have_a_format:1
  xbuf:0x1.5p+5:   have_a_format:1
  
  can you share OS/version/architecture, and also run your program with  env
 - ./a.out  to rule out any environment setup?
