/**
|
|
* Get the real part of a complex number.
|
|
* For a complex number `a + bi`, the function returns `a`.
|
|
*
|
|
* For matrices, the function is evaluated element wise.
|
|
*
|
|
* Syntax:
|
|
*
|
|
* math.re(x)
|
|
*
|
|
* Examples:
|
|
*
|
|
* const a = math.complex(2, 3)
|
|
* math.re(a) // returns number 2
|
|
* math.im(a) // returns number 3
|
|
*
|
|
* math.re(math.complex('-5.2i')) // returns number 0
|
|
* math.re(math.complex(2.4)) // returns number 2.4
|
|
*
|
|
* See also:
|

*
|
|
* im, conj, abs, arg
|
|
*
|
|
* @param {number | BigNumber | Complex | Array | Matrix} x
|
|
* A complex number or array with complex numbers
|
|
* @return {number | BigNumber | Array | Matrix} The real part of x
