The function @code{quadmath_snprintf} converts a @code{__float128} floating-point
|
|
|
|
number into a string. It is a specialized alternative to @code{snprintf}, where
|
|
|
|
the format string is restricted to a single conversion specifier with @code{Q}
|
|
|
|
modifier and conversion specifier @code{e}, @code{E}, @code{f}, @code{F}, @code{g},
|
|
|
|
@code{G}, @code{a} or @code{A}, with no extra characters before or after the
|
|
|
|
conversion specifier. The @code{%m$} or @code{*m$} style must not be used in
|
|
|
|
the format.
