It is. From printf() man page:
0 The value should be zero padded. For d, i, o, u, x, X, a, A, e,
E, f, F, g, and G conversions, the converted value is padded on
the left with zeros rather than blanks. If the 0 and - flags
both appear, the 0 flag is ignored. If a precision is given
with a numeric conversion (d, i, o, u, x, and X), the 0 flag is
ignored. For other conversions, the behavior is undefined.
But please also remember that flag precedence may depend on type of
conversion.
In hb_snpritf() I tried to replicate the explicitly defined and also some
undocumented modifier precedences.
It will be good to fully replicate it also in the .prg SPRINTF wrapper.
best regards,
Przemek
