Indeed Archie, the scientific representation is what I took it to be. E.g. "the most accepted value of the speed of light till date is 299792458 m/s which is taken as 3×10^8 ms-¹ after rounding off." The degree of accuracy is affected by the rounding process - something a commercial application would not countenance. The other "floating point" is merely a decimal alignment, which is achieved by padding the least significant digits (the right hand side) thus 12.12 + 9.3657 becomes 12.1200 + 9.3657, the operands when added, multiplied, etc can then be trimmed, truncated or rounded to a specified requirement (in ASX case 1 decimal, rounded). The method of padding will depend on the programming language, technology and compiler plus the inventiveness of the programmer (I once programmed a computer that had no "multiply" function, so to multiply X*Y meant I had to add "X" to itself "Y-1" times). I have worked on 24, 36 and 64 bit systems although there are others. Like in all spheres of industry, the jargon needs to be defined - the word "sow" means something different to a pig ignorant arable farmer than a livestock farmer (pun intended), even though they are both in the agricultural business.
It is indeed quiet here, I am only checking in rarely at present.
