pub struct Decimal { /* fields omitted */ }
Expand description
Creates a Decimal from parts without boundary checking.
User have to guarantee that int_val has at most 38 tens digits and scale ranges from [-126, 130].
Creates a Decimal from parts.
int_val has at most 38 tens digits, scale ranges from [-126, 130].
Consumes the Decimal, returning (int_val, scale, negative).
Returns the precision, i.e. the count of significant digits in this decimal.
Returns the scale, i.e. the count of decimal digits in the fractional part.
A positive scale means a negative power of 10.
Returns true if the sign bit of the decimal is negative.
Returns true if the sign bit of the decimal is positive.
Computes the absolute value of self.
Encodes self to writer as binary bytes.
Returns total size on success, which is not larger than MAX_BINARY_SIZE.
Encodes self to writer as binary bytes.
Returns total size on success, which is not larger than MAX_BINARY_SIZE.
The only different from Decimal::encode is it will compact encoded bytes
when self is zero or small positive integer.
Decodes a Decimal from binary bytes.
Computes the smallest integer that is greater than or equal to self.
Computes the largest integer that is equal to or less than self.
Truncate a value to have scale digits after the decimal point.
We allow negative scale, implying a truncation before the decimal
point.
Round a value to have scale digits after the decimal point.
We allow negative scale, implying rounding before the decimal
point.
Do bounds checking and rounding according to precision and scale.
Returns true if overflows.
Normalize a Decimal’s scale toward zero.
Add two decimals,
returning None if overflow occurred.
Subtract one decimal from another,
returning None if overflow occurred.
Calculate the product of two decimals,
returning None if overflow occurred.
Checked decimal division.
Computes self / other, returning None if other == 0 or the division results in overflow.
Checked decimal remainder.
Computes self % other, returning None if rhs == 0 or the division results in overflow.
Computes the square root of a decimal,
returning None if self is negative or the results in overflow.
Formats the decimal, using scientific notation depending on the width.
Raise self to the power of exponent, where self and exponent
are both decimal, returning None if self == 0 at the same time
exponent is negative or self is negative at the same time
exponent is a fraction or the result overflowed.
Computes the natural logarithm of self,
returning None if self is negative or self == 0.
Computes the nature exponential of self,
returning None if the result overflowed.
