Just a few of more points.

- Floating point is for scientific and numerical computations - stress on scientific here.

- Floating point is CPU specific - remember the Pentium 'floating point math' debacle a few years back in which identical computers were doing scientific calculations a a number of the computers did not agree ? The difference was in the CPU 'build level'.

- CPAs, MBAs and PhDs along with managers and directors that design and use application systems with float for numerical calculation that require precision are one 'M' away from being 'Mormons' !
