In computing, a normal number is a non-zero number in a floating-point representation which is within the balanced range supported by a given floating-point format: it is a floating point number that can be represented without leading zeros in its significand. The magnitude of the smallest normal number in a format is given by bemin, where b is the base (radix) of the format (usually 2 or 10) and emin depends on the size and layout of the format. Similarly, the magnitude of the largest normal number in a format is given by bemax × (b − b1−p), where p is the precision of the format in digits and emax is (−emin)+1. In the IEEE 754 binary and decimal formats, b, p, emin, and emax have the following values: For example, in the smallest decimal format, the range of positive normal numbers is 10−95 through 9.999999 × 1096. Non-zero numbers smaller in magnitude than the smallest normal number are called subnormal (or denormal) numbers. Zero is neither normal nor subnormal. (Wikipedia).

Imaginary numbers are any numbers that include the imaginary number i. A mix of imaginary and real numbers gives you what’s called a complex number. The primary reason we use imaginary numbers is to give us a way to find the root (radical) of a negative number. There’s no way to use real

Abstract : Recall that normality is a elementary form of randomness: an infinite word is normal to a given alphabet if all blocks of symbols of the same length occur in the word with the same asymptotic frequency. We consider a notion of independence on pairs of infinite words formalising

Welcome to Quantitative Risk Management (QRM). In this lesson, we play with R to deal with VaR and ES. We show how to compute them empirically, but also in the case of normality. We then show that normality tends to underestimate tail risk, as observable in actual financial data. The pdf
