The source code for an entrophy testing method I am trying to incorporate in my
program has the comment:

/* Bytes used as Monte Carlo co-ordinates.
This should be no more bits than the mantissa
of your "double" floating point type. */

#define MONTEN	6

I cannot determine from either the .asm or the .h or the help files how many
bits are in the mantissa.

long doubles have a 64 bit mantissa, a 15 bit exponent, and a 1 bit sign.

I'd really like to see a SEF float format with two or more sign bits. :-)
