msgid ":mod:`cmath` --- Mathematical functions for complex numbers"
#: library/cmath.rst:9
"This module provides access to mathematical functions for complex numbers.  "
"The functions in this module accept integers, floating-point numbers or "
"complex numbers as arguments. They will also accept any Python object that "
"has either a :meth:`~object.__complex__` or a :meth:`~object.__float__` "
"method: these methods are used to convert the object to a complex or "
"floating-point number, respectively, and the function is then applied to the "
"result of the conversion."
#: library/cmath.rst:18
"For functions involving branch cuts, we have the problem of deciding how to "
"define those functions on the cut itself. Following Kahan's \"Branch cuts "
"for complex elementary functions\" paper, as well as Annex G of C99 and "
"later C standards, we use the sign of zero to distinguish one side of the "
"branch cut from the other: for a branch cut along (a portion of) the real "
"axis we look at the sign of the imaginary part, while for a branch cut along "
"the imaginary axis we look at the sign of the real part."
#: library/cmath.rst:26
"For example, the :func:`cmath.sqrt` function has a branch cut along the "
"negative real axis. An argument of ``complex(-2.0, -0.0)`` is treated as "
"though it lies *below* the branch cut, and so gives a result on the negative "
"imaginary axis::"
#: library/cmath.rst:34
"But an argument of ``complex(-2.0, 0.0)`` is treated as though it lies above "
"the branch cut::"

#: library/cmath.rst:44
"A Python complex number ``z`` is stored internally using *rectangular* or "
"*Cartesian* coordinates.  It is completely determined by its *real part* ``z."
"real`` and its *imaginary part* ``z.imag``.  In other words::"
#: library/cmath.rst:51
"*Polar coordinates* give an alternative way to represent a complex number.  "
"In polar coordinates, a complex number *z* is defined by the modulus *r* and "
"the phase angle *phi*. The modulus *r* is the distance from *z* to the "
"origin, while the phase *phi* is the counterclockwise angle, measured in "
"radians, from the positive x-axis to the line segment that joins the origin "
#: library/cmath.rst:58
"The following functions can be used to convert from the native rectangular "
"coordinates to polar coordinates and back."
#: library/cmath.rst:63
"Return the phase of *x* (also known as the *argument* of *x*), as a float. "
"``phase(x)`` is equivalent to ``math.atan2(x.imag, x.real)``.  The result "
"lies in the range [-\\ *π*, *π*], and the branch cut for this operation lies "
"along the negative real axis.  The sign of the result is the same as the "
"sign of ``x.imag``, even when ``x.imag`` is zero::"
#: library/cmath.rst:77
"The modulus (absolute value) of a complex number *x* can be computed using "
"the built-in :func:`abs` function.  There is no separate :mod:`cmath` module "
"function for this operation."
#: library/cmath.rst:84
"Return the representation of *x* in polar coordinates.  Returns a pair ``(r, "
"phi)`` where *r* is the modulus of *x* and phi is the phase of *x*.  "
"``polar(x)`` is equivalent to ``(abs(x), phase(x))``."

"specified, returns the natural logarithm of *x*. There is one branch cut, "
"from 0 along the negative real axis to -∞."

"Return the arc sine of *x*. This has the same branch cuts as :func:`acos`."

"``False`` otherwise."
#: library/cmath.rst:226
"Whether or not two values are considered close is determined according to "
"given absolute and relative tolerances."
#: library/cmath.rst:229
"*rel_tol* is the relative tolerance -- it is the maximum allowed difference "
"between *a* and *b*, relative to the larger absolute value of *a* or *b*. "
"For example, to set a tolerance of 5%, pass ``rel_tol=0.05``.  The default "
"tolerance is ``1e-09``, which assures that the two values are the same "
"within about 9 decimal digits.  *rel_tol* must be greater than zero."

"*abs_tol* is the minimum absolute tolerance -- useful for comparisons near "
"zero. *abs_tol* must be at least zero."
#: library/cmath.rst:238

"max(abs(a), abs(b)), abs_tol)``."
#: library/cmath.rst:241
"The IEEE 754 special values of ``NaN``, ``inf``, and ``-inf`` will be "
"handled according to IEEE rules.  Specifically, ``NaN`` is not considered "
"close to any other value, including ``NaN``.  ``inf`` and ``-inf`` are only "
"considered close to themselves."

"Note that the selection of functions is similar, but not identical, to that "
"in module :mod:`math`.  The reason for having two modules is that some users "
"aren't interested in complex numbers, and perhaps don't even know what they "
"are.  They would rather have ``math.sqrt(-1)`` raise an exception than "
"return a complex number. Also note that the functions defined in :mod:"

"A note on branch cuts: They are curves along which the given function fails "
"to be continuous.  They are a necessary feature of many complex functions.  "
"It is assumed that if you need to compute with complex functions, you will "
