On this page assembler routines for the switching of the rounding mode can be found.

---

All these routines are from the PROFIL/BIAS package.

• fp68000.s
• fpHPPA.s
• fpRS6000.s
• fpSparc.s

An extra routine for SGI.

• fpSGI.c (thanks to Helmut Jarausch, RWTH Aachen)

Some compilers changed the conventions concerning the use of underscores. This may cause some difficulties. Trouble like this was reported by users of Solaris and Linux.

For INTLAB and b4m the routine setround can be downloaded as source code and (for some architectures) in compiled form:
