    Decimal('1.414')\n\

Unlike other operations, if the length of the coefficient after the quantize\n\
operation would be greater than precision, then an InvalidOperation is signaled.\n\
This guarantees that, unless there is an error condition, the quantized exponent\n\

Also unlike other operations, quantize never signals Underflow, even if the\n\

If the exponent of the second operand is larger than that of the first, then\n\

Return the result of rotating the digits of the first operand by an amount\n\
specified by the second operand.  The second operand must be an integer in\n\
the range -precision through precision. The absolute value of the second\n\
operand gives the number of places to rotate. If the second operand is\n\
positive then rotation is to the left; otherwise rotation is to the right.\n\
The coefficient of the first operand is padded on the left with zeros to\n\
length precision if necessary. The sign and exponent of the first operand are\n\
unchanged.\n\

Test whether self and other have the same exponent or whether both are NaN.\n\

Return the result of shifting the digits of the first operand by an amount\n\
specified by the second operand.  The second operand must be an integer in\n\
the range -precision through precision. The absolute value of the second\n\
operand gives the number of places to shift. If the second operand is\n\
positive, then the shift is to the left; otherwise the shift is to the\n\
right. Digits shifted into the coefficient are zeros. The sign and exponent\n\
of the first operand are unchanged.\n\
\n");

PyDoc_STRVAR(doc_sqrt,

Return the square root of the argument to full precision. The result is\n\
correctly rounded using the ROUND_HALF_EVEN rounding mode.\n\

"to_eng_string($self, /, context=None)\n--\n\n\
Convert to an engineering-type string.  Engineering notation has an exponent\n\
which is a multiple of 3, so there are up to 3 digits left of the decimal\n\
place. For example, Decimal('123E+1') is converted to Decimal('1.23E+3').\n\

rounding mode of the current default context is used.\n\

Round to the nearest integer without signaling Inexact or Rounded.  The\n\
