In Macforth (or Macforth Plus), there is a "Math Toolkit" which does
floating point number crunching and is an alternative to SANE. It is
extremely fast. For example, it is faster than integer arithematics in
some calculations (in Macforth). To sum the reciprocal of 1 to 10001,
MS Basic double precision (on a Mac) takes 68 seconds, single precision
takes 22 seconds, TRUE BASIC (on a Mac) takes 7 seconds, Macforth scaled
integer takes 4.6, and the Math Toolkit and Macforth (in floating point)
takes 3.6 seconds. On an IBM AT with Turbo Pascal 3.0, 9 seconds without
the math chip, and 4.0 seconds with 80287 math chip. It seems incredible,
but it is true! Math Toolkit is from Mosaic Industries of Mountain View.
