[locale.money.put.virtuals] (original) (raw)

Effects: Writes characters to s according to the format specified by a moneypunct<charT, Intl> facet reference mp and the character mapping specified by a ctype<charT> facet reference ctobtained from the locale returned by str.getloc(), and str.flags().

The argument units is transformed into a sequence of wide characters as if byct.widen(buf1, buf1 + sprintf(buf1, "%.0Lf", units), buf2) for character buffers buf1 and buf2.

If the first character in digits or buf2is equal to ct.widen('-'), then the pattern used for formatting is the result of mp.neg_format(); otherwise the pattern is the result of mp.pos_format().

Digit characters are written, interspersed with any thousands separators and decimal point specified by the format, in the order they appear (after the optional leading minus sign) indigits or buf2.

In digits, only the optional leading minus sign and the immediately subsequent digit characters (as classified according to ct) are used; any trailing characters (including digits appearing after a non-digit character) are ignored.

Calls str.width(0).
