Remember that the square of real numbers is never less than 0, so the value of x that solves x 2 = –1 can’t be real. We call it an imaginary number and write i = √ –1. Any other imaginary number is a multiple of i, for example 2 i or –0.5 i.For a positive number, the argument is always 0; the argument of a negative number is \(\pi\); and the argument of 0 is undefined and returns nan. So the arg function will never nest greater than 3 levels since at the 4th application, the result must be nan; for a real number, nan is returned on the 3rd application. Parameters: arg: ExprFor example, R3>0 R > 0 3 denotes the positive-real three-space, which would read R+,3 R +, 3 in non-standard notation. Addendum: In Algebra one may come across the symbol R∗ R ∗, which refers to the multiplicative units of the field (R, +, ⋅) ( R, +, ⋅). Since all real numbers except 0 0 are multiplicative units, we have. Real numbers. Real numbers are the set of numbers that consists of both rational and irrational numbers. They can either count to be positive or negative. Generally, real numbers are denoted by the alphabetical symbol ‘R’.
