Somewhat surprisingly, clang 10's long double on a mac is implemented with 64 mantissa digits (bits) (LDBL_MANT_DIG = 64) so the information as presented is correct for clang on a MacBook Pro 2017 with a 2.8 GHz Intel Core i7. So, is this a bug? Well, perhaps, but not in enquire.c. Experimental usage shows that only 10 bytes (79 bits) are actually used. This is clearly implemented as an x87 80-bit floating point number. |
