When the following program is run:

	main()
	{
		printf("7e-7 = %f\n", 7e-7);
	}

I get the following results on the following MIPS-based systems:

	RISC ULTRIX 3.0			7e-7 = 0.000000
	SGI IRIX 3.2			7e-7 = 0.000000
	MIPS OS 1.0			7e-7 = 0.000001

Looks like yet another compiler bug which MIPS has fixed but DEC and
SGI have not yet picked up.

Would someone please run the same program on the latest version of RISC
ULTRIX (4.0) and SGI IRIX (3.3) and see if DEC or SGI have fixed the
problem in their later releases?

Thanks.
