I have a basic notation/convention question. I'm writing a program in Pascal programming language which does computations in the rational number field (ℚ). For that i defined a data type, which represents a vulgar fraction:
type Rational = record Numerator: Integer; Denominator: Natural; end;
I hope this declaration is pretty obvious for anyone who know about fractions regardless Pascal knowledge. However, while working with this data type i figured out what what
Denominator identifier is unconveniently long. Eg, simple notation, which is usualy compact on the paper (on in MathCAD) becomes quite large when expressed in Pascal:
C.Numerator := A.Numerator * B.Denominator + A.Denominator * B.Numerator;
So, my question is: What is common and widely recognized abbreviations for Numerator and Denominator terms for Anglophone mathematicians? As we have
Im(C) brief and common notation when referring to the components of complex number.
