Complex numbers j
In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation $${\displaystyle i^{2}=-1}$$; every complex number can be expressed in the form $${\displaystyle a+bi}$$, … See more A complex number is a number of the form a + bi, where a and b are real numbers, and i is an indeterminate satisfying i = −1. For example, 2 + 3i is a complex number. This way, a complex number is defined as a See more The solution in radicals (without trigonometric functions) of a general cubic equation, when all three of its roots are real numbers, … See more Equality Complex numbers have a similar definition of equality to real numbers; two complex numbers a1 + b1i and a2 + b2i are equal if and only if both … See more Construction as ordered pairs William Rowan Hamilton introduced the approach to define the set $${\displaystyle \mathbb {C} }$$ of complex numbers as the set $${\displaystyle \mathbb {R} ^{2}}$$ of ordered pairs (a, b) of real numbers, in which the following … See more A real number a can be regarded as a complex number a + 0i, whose imaginary part is 0. A purely imaginary number bi is a complex number 0 + bi, whose real part is zero. As with … See more A complex number z can thus be identified with an ordered pair $${\displaystyle (\Re (z),\Im (z))}$$ of real numbers, which in turn may be interpreted as coordinates of a point in a two-dimensional space. The most immediate space is the Euclidean plane with suitable … See more Field structure The set $${\displaystyle \mathbb {C} }$$ of complex numbers is a field. Briefly, this means that the following facts hold: first, any two complex … See more

WebJul 17, 2014 · The way numbers are parsed either by the language parser (in source code) or by the built-in functions (int, float, complex) should not be localizable or configurable in any way; that's asking for huge disappointments down the road. If you want to parse complex numbers using 'i' instead of 'j', you have plenty of solutions available already.
