what is fixed point in mathematics. Fixed-point math is most commonly used for systems that lack an FPU or when you need a few more ounces of performance or precision than the standard floating point types can provide hint. What is the maximum number of fixed points of a permutation s from S12 if the subgroup generated by s in the group S12 composition of permutations o has 12 elements.
Not all functions have fixed points. In mathematics a fixed point sometimes shortened to fixpoint also known as an invariant point of a function is an element of the functions domain that is mapped to itself by the function. For example if given fixed-point representation is IIIIFFFF then you can store minimum value is 00000001 and maximum value is 99999999.
With floating-point representation the placement of the decimal point can float relative to the significant digits of the number.
Note that P contains 2Nelements. Fixed-point number representation can be compared to the more complicated floating-point number representation. Fixed point method allows us to solve non linear equations. Through the simple use of integer operations the math can be efficiently performed with very little loss of accuracy.
