FloatParts class - ieee754 library

Constructors

FloatParts(int mantissa, int exponent, {bool forceNegative = false}): Create the parts for the number M * 2^E, where M is the mantissa and E is the exponent.
factory
FloatParts.fromDouble(double value): Parse FloatParts from a double.
factory
FloatParts.fromFloat128Bytes(Uint8List bytes, [Endian e = Endian.big]): Parse FloatParts from a single IEEE754 float128 encoded as bytes.
factory
FloatParts.fromFloat16Bytes(Uint8List bytes, [Endian e = Endian.big]): Parse FloatParts from a single IEEE754 float16 encoded as bytes.
factory
FloatParts.fromFloat32Bytes(Uint8List bytes, [Endian e = Endian.big]): Parse FloatParts from a single IEEE754 float32 encoded as bytes.
factory
FloatParts.fromFloat64Bytes(Uint8List bytes, [Endian e = Endian.big]): Parse FloatParts from a single IEEE754 float64 encoded as bytes.
factory
FloatParts.withBigMantissa(BigInt mantissa, int exponent, {bool forceNegative = false}): Create the parts for the number M * 2^E, where M is the mantissa and E is the exponent.
