NES::Float Class Reference

Float precision are inexact, variable-precision numeric types. Inexact means that some values cannot be converted exactly to the internal format and are stored as approximations, so that storing and retrieving a value might show slight discrepancies. More...

Detailed Description

Float precision are inexact, variable-precision numeric types. Inexact means that some values cannot be converted exactly to the internal format and are stored as approximations, so that storing and retrieving a value might show slight discrepancies.

Constructor & Destructor Documentation

Float()

NES::Float::Float ( int8_t  bits, double  lowerBound, double  upperBound  )

inlinenoexcept

Constructs a new Float type.

Parameters

bits	the number of bits in which this type is represented.
lowerBound	the lower bound, which is contained in that float.
upperBound	the upper bound, which is contained in that float.

~Float()

NES::Float::~Float ( )

Member Function Documentation

equals()

bool NES::Float::equals ( DataTypePtr  otherDataType )

overridevirtual

Checks if two data types are equal.

Parameters

otherDataType

Returns

Implements NES::DataType.

References NES::Numeric::bits, lowerBound, and upperBound.

isFloat()

bool NES::Float::isFloat ( ) const

inlineoverridevirtual

Checks if this data type is Float.

Reimplemented from NES::DataType.

join()

DataTypePtr NES::Float::join ( DataTypePtr  otherDataType )

overridevirtual

Calculates the joined data type between this data type and the other. If they have no possible joined data type, the coined type is Undefined. Floats, we can join with all numeric data types.

Parameters

other

data type

Returns

DataTypePtr joined data type

Implements NES::DataType.

Here is the call graph for this function:

toString()

std::string NES::Float::toString ( )

overridevirtual

Returns a string representation of the data type.

Returns

string

Implements NES::DataType.
