KMaxPrecision

const TIntKMaxPrecision

KPrecisionLimit

const TIntKPrecisionLimit

This constant specifies the maximum number of significant digits available with floating point computations. Rounding and string formatting methods will not use more digits than this.

KIEEEDoubleInjectivePrecision

const TIntKIEEEDoubleInjectivePrecision

Let D be the set of real numbers exactly representable by an IEEE-754 'double' For any positive integer n let X_n be the set of real numbers with an exact decimal representation using n significant digits. Let r_n : D -> X_n be defined by r_n(x)=y such that |y-x| = inf { |z-x| : z in X_n } and (in the case where two such y exist) that the last significant digit in the decimal representation of y is even. This constant is the least n such that r_n is injective.
