Copies a 128-bit decimal floating-point operand x to a destination in the same format,
changing the sign to positive.
Returns a result of decimal floating-point addition, [Decimal128] + [Decimal128] -> [Decimal128]
Copies a decimal floating-point operand x to a destination in the same format, with no change.
Returns s result of decimal floating-point division, [Decimal128] / [Decimal128] -> [Decimal128]
Returns the value of
e raised to the xth power.Converts 32-bit signed integer to 128-bit decimal floating-point number.
Converts 64-bit signed integer to 128-bit decimal floating-point number.
Converts a decimal floating-point value represented in string format (decimal character sequence)
to 128-bit decimal floating-point format (binary encoding).
Converts 32-bit unsigned integer to 128-bit decimal floating-point number.
Converts 64-bit unsigned integer to 128-bit decimal floating-point number.
Returns the exponent e of x, a signed integral value, determined as though x
were represented with infinite range and minimum exponent.
Returns
true if and only if x is zero, subnormal or normal (not infinite or NaN).Returns
true if and only if x has negative sign.Returns
true if and only if x is +0 or -0.Returns natural logarithm of
x.Returns the canonicalized floating-point number y if x < y,
x if y < x, the canonicalized floating-point number if one operand
is a floating-point number and the other a quiet NaN.
Otherwise it is either x or y, canonicalized.
Returns the canonicalized floating-point number x if x < y,
y if y < x, the canonicalized floating-point number if one operand
is a floating-point number and the other a quiet NaN.
Otherwise it is either x or y, canonicalized.
Returns s result of decimal floating-point multiplication, [Decimal128] * [Decimal128] -> [Decimal128]
Returns the same value as
x but with reversed sign.Returns decimal floating-point power.
Returns the quantum of a finite argument as a signed integer value.
Returns the number which is equal in value (except for any rounding) and sign
to the first (left-hand) operand and which has an exponent set to be equal
to the exponent of the second (right-hand) operand.
Returns the quantum of a finite argument.
If x is infinite, the result is +Inf. If x is NaN, the result is NaN.
