+/* This template provides testing for the *cvt family of functions,
+ which deal with double or long double types. In order to use the
+ template, the following macros must be defined before inclusion of
+ this template:
+
+ FLOAT: The floating-point type, i.e. double or long double.
+
+ ECVT: Appropriate *ecvt function for FLOAT, i.e. ecvt or qecvt.
+ FCVT: Likewise for *fcvt, i.e. fcvt or qfcvt.
+ ECVT_R: Likewise for *ecvt_r, i.e. ecvt_r or qecvt_r.
+ FCVT_R: Likewise for *fcvt_r, i.e. fcvt_r or qfcvt_r.
+
+ PRINTF_CONVERSION: The appropriate printf conversion specifier with
+ length modifier for FLOAT, i.e. "%f" or "%Lf".
+
+ EXTRA_ECVT_TESTS: Additional tests for the ecvt or qecvt function
+ that are only relevant to a particular floating-point type and
+ cannot be represented generically. */
