How make Float80 bridge with long double math.h c functions?
I resorts to use some orrible hacks like these:
// in f80.h
extern void sqrt_f80( void *result, const void *v );
extern void pow_f80( void *result, const void *v, const void *e );
...
// in f80.c
void sqrt_f80( void *result, const void *v ) { *(long double *)result =
sqrtl( *(const long double *)v ); }
void pow_f80( void *result, const void *v, const void *e ) { *(long double
*)result = powl( *(const long double *)v,*(const long double *)e ); }
…
// in f80.swift
func sqrt( _ a:Float80 ) -> Float80 { var result = Float80(); var v
= a; sqrt_f80( &result, &v ); return result; }
func pow( _ a:Float80,_ e:Float80 ) -> Float80 { var result = Float80(); var v1
= a; var v2 = e; pow_f80( &result, &v1, &v2 ); return result; }
There is an easier way?
P.S. Sorry for my bad english.
