Number

Class to represent Numbers in dutils.

class Number : Mtype!NumberContainer {

this(NumberContainer num);

this(ulong precision);

dstring toDstring();

void fromDstring(dstring from);

bool applyOp(dstring op, Mtype!W rhs);

Number applyOpResult(dstring op, Mtype!W rhs);

bool opEquals(Number rhs);

}

Constructors

this this(NumberContainer num): Constructs a Number.
this this(ulong precision): Constructs a Number using precision only.

Functions

applyOp bool applyOp(dstring op, Mtype!W rhs): Applies an operator to a Number given the rhs.
applyOpResult Number applyOpResult(dstring op, Mtype!W rhs): The result of applying an operator to a Number.
fromDstring void fromDstring(dstring from): Serializes a dstring to a Number.
opEquals bool opEquals(Number rhs): Detrmine if two Numbers are equal.
toDstring dstring toDstring(): Represents a Number as a dstring.

Examples

BigInt a = 1;
immutable BigInt b = -1;
immutable long c = 0;
Number e = new Number(NumberContainer(a,b,c));
a = 2;
Number f = new Number(NumberContainer(a,b,c));
e.applyOp("/", f);
assert(e.val == NumberContainer(BigInt(6), BigInt(-2), -1L));
assert(e.toDstring == ".6-.2i"d);
f = new Number(NumberContainer(BigInt(6), BigInt(0), 1L));
assert(f.toDstring == "60+00i"d);
auto g = f.toDstring;
