Class complex
Complex number type.
The constructor (complex) is in the global namespace (global.complex).
Complex numbers support basic operations +,-,*,/ among themselves or with regular numbers.
The real or imaginary part can be accessed with .r or .i (i.e. z.r or z.i). This works for setting and getting the value.
Methods
| complex:set (x[, y=0]) | Set complex number from another, or 1 or 2 real numbers. |
| complex:conj () | Return complex conjugate. |
| complex:peq (z) | Add another number to this one (+=). |
| complex:meq (z) | Subtract another number from this one (-=). |
| complex:sqrt () | Return square root. |
| complex:norm2 () | Return absolute value squared. |
Methods
- complex:set (x[, y=0])
-
Set complex number from another, or 1 or 2 real numbers.
Parameters:
- x number or complex real part or complex value
- y number imaginary part (only if x is not complex) (default 0)
- complex:conj ()
-
Return complex conjugate.
Returns:
-
complex
conjugate of self
- complex:peq (z)
-
Add another number to this one (+=).
Parameters:
- z real or complex number to add to self
- complex:meq (z)
-
Subtract another number from this one (-=).
Parameters:
- z real or complex number to subtract from self
- complex:sqrt ()
-
Return square root.
Returns:
-
complex
square root of self
- complex:norm2 ()
-
Return absolute value squared.
Returns:
-
complex
absolute value squared of self
