- Hi, netters :
-
- I only know it's available to use a 128 bits floating point number on VAX
-
- FORTRAN (quad precision: REAL*16). And the VAX FORTRAN also support the math
-
- library functions with a quad precision floating point number , just as
-
- REAL*16 QSIN(REAL*16), REAL*16 QCOS(REAL*16), ..... etc. But I can't use the
-
- 128 bits floating point number on VAX C, it just allow to using the double
-
- precison type (64 bits). And it also only support the double precison type of
-
- the math library functions.
-
- Could anyone tell me how to use quad precision type on VAX C ? Or does it
-
- have another solution to get 128 bits precision on VAX C ? By the way, the
-
- "/G_FLOATING on compiling" seems useful. How does it work ?
-
- Thanks for advance !!!
