assign(boolean, int, long, long) - Method in class com.mvohm.quadruple.Quadruple: Builds a Quadruple value from the given low-level parts and assigns it to the instance.
Treats the exponent parameter as the biased exponent value, so that its value equal to EXPONENT_OF_ONE (0xFFFF_FFFEL) corresponds to the Quadruple value of 1.0.
assign(double) - Method in class com.mvohm.quadruple.Quadruple: Converts the given value to quadruple and assigns it to the instance.
Expands exponent to 32 bits preserving its value, and expands mantissa to 128 bits, filling with zeroes the least significant 76 bits that absent in the double value.
assign(int, long, long) - Method in class com.mvohm.quadruple.Quadruple: Builds a non-negative Quadruple value from the given low-level parts and assigns it to the instance.
Treats the exponent parameter as the biased exponent value, so that its value equal to EXPONENT_OF_ONE (0xFFFF_FFFEL) corresponds to the Quadruple value of 1.0.
assign(long) - Method in class com.mvohm.quadruple.Quadruple: Converts the given value to quadruple and assigns it to the instance.
To find the mantissa, shifts the bits of the absolute value of the parameter left, so that its most significant non-zero bit (that stands for the 'implicit unity' of the floating point formats) gets shifted out, then corrects the exponent depending on the shift distance and sets the sign in accordance with the initial sign of the parameter.
assign(long[]) - Method in class com.mvohm.quadruple.Quadruple: Builds a Quadruple from the low-level parts given as an array of long.
The elements of the array are expected to contain the following values:
assign(Quadruple) - Method in class com.mvohm.quadruple.Quadruple: Assigns the given value to the instance (copies the values of the private fields of the parameter to the respective fields of this instance).
assign(String) - Method in class com.mvohm.quadruple.Quadruple: Parses the given String that is expected to contain floating-point value in any conventional string form or a string designation of one of special values, and assigns the corresponding value to the instance.
Parsing is case-insensitive.
The admittable string designations for special values are the following: "Quadruple.MIN_VALUE", "MIN_VALUE", "Quadruple.MAX_VALUE", "MAX_VALUE", "Quadruple.MIN_NORMAL", "MIN_NORMAL", "Quadruple.NaN", "NaN", "Quadruple.NEGATIVE_INFINITY", "NEGATIVE_INFINITY", "-INFINITY", "Quadruple.POSITIVE_INFINITy", "POSITIVE_INFINITY", "INFINITY", "+INFINITY".
If the exact value of the number represented by the input string is greater than the nearest exact Quadruple value by less than 0.5 - 1e-17 of the least significant bit of the mantissa of the latter, it gets rounded down to the aforementioned Quadruple value.
If it is greater by 0.5 LSB or more, it gets rounded up to the greater adjacent Quadruple value.
In cases when difference between the input value and the nearest Quadruple value is between (0.5 - 1e-17) * LSB and 0.5 * LSB, the direction of the rounding is unpredictable.
assign(BigDecimal) - Method in class com.mvohm.quadruple.Quadruple: Converts the given value to Quadruple, and assigns it to the instance.
If the source value can't be represented as Quadruple exactly, it gets rounded to a 129-bit value (implicit unity + 128 bits of the fractional part of the mantissa) according to the 'half-up' rule.
assignIeee754(byte[]) - Method in class com.mvohm.quadruple.Quadruple: Assigns the value of a IEEE-754 quadruple value passed in as an array of 16 bytes containing the 128 bits of the IEEE-754 quadruple to the given instance.
The passed in array of longs is expected to be big-endian, in other words the value[0] should contain the sign bit, and the high-order 7 bits of the IEEE-754 quadruple's exponent, and the value[15] is expected to contain the least significant 8 bits of the significand.
The argument remains unchanged.
assignIeee754(long[]) - Method in class com.mvohm.quadruple.Quadruple: Assigns the value of a IEEE-754 quadruple value passed in as an array of two longs containing the 128 bits of the IEEE-754 quadruple to the given instance.
