math programming

math programming in sepples is rather complicated to the point that books are written on the subject. first there is the factor of limited precision of types, like how much a double or long double can hold. so is it preferable to use dynamic programming languages like Python and Perl that dont have any limit on length of floating point precision? and is it true that twos compliment creates gaps in the number line? do calculators use twos compliment? I noticed some high end calculators use the old Z80 or 6502 CPUs, but is there added arithmetic circuitry or can you rely on these standard CPUs to provide sufficient math processing?

thats interesting info you give, I didnt know real numbers were unattainable, I thought only irrational numbers were unattainable.

>I don't know what you mean by "special math circuitry".
I heard that PowerPC CPUs have higher floating point precision than the floating point math unit that is in x86 CPUs, so I would imagine that calculators are built with this special high precision floating point circuitry.
