Class Documentation

class SymEngine::RealDouble : public SymEngine::Number

RealDouble Class to hold double values.

Public Functions

RealDouble(double i)

Constructor of RealDouble class.

hash_t __hash__() const

Return

size of the hash

bool __eq__(const Basic &o) const

Equality comparator

Return

whether the 2 objects are equal

Parameters

• o: - Object to be compared with

int compare(const Basic &o) const

Returns -1, 0, 1 for this < o, this == o, this > o. This method is used when you want to sort things like x+y+z into canonical order. This function assumes that o is the same type as this. Use __cmp__ if you want general comparison.

bool is_positive() const

Return

true if positive

bool is_negative() const

Return

true if negative

double as_double() const

Return

self as a double

bool is_exact() const

Return

true if this number is an exact number

Evaluate &get_eval() const

Get Evaluate singleton to evaluate numerically.

bool is_zero() const

Return

true when equals to 0

bool is_one() const

Return

false

bool is_minus_one() const

Return

false

bool is_complex() const

Return

false
