Constructors

this
this(T value)

Constructs a Decimal data type using the specified _value

Members

Functions

opAssign
auto ref opAssign(T value)

Implementation of assignnment operator. It supports the same semantics as the constructor.

opBinary
auto opBinary(T value)
opBinaryRight
auto opBinaryRight(T value)

Implementation of binary and assignment operators (+, -, *, /, %, ^^).

opCast
T opCast()

Implementation of cast operator. Supported casts: integral, floating point, _decimal, char, bool Exceptions:

integral✓✓✓✓
char✓✓✓✓
float✓✓✓
bool
decimal✓✓✓
opCmp
float opCmp(T value)

Implementation of comparison operator. Supported types : _decimal, floating point, integral, char

thisValueResultInvalid
NaNanyNaN✓
anyNaNNaN✓
anyany±1.0, 0.0
opEquals
bool opEquals(T value)

Implementation of == operator. This operation is silent, no exceptions are thrown. Supported types : _decimal, floating point, integral, char

opOpAssign
auto opOpAssign(T value)

Implementation of binary and assignment operators (+, -, *, /, %, ^^).

opUnary
auto opUnary()

Implementation of +/- unary operators. These operations are silent, no exceptions are thrown

opUnary
auto ref opUnary()

Implementation of ++/-- unary operators. Exceptions:

Value++/--InvalidOverflowInexact
NaNNaN✓
±∞±∞
anyany✓✓
toHash
size_t toHash()

Returns a unique hash of the _decimal value suitable for use in a hash table. Notes: This function is not intended for direct use, it's provided as support for associative arrays.

toString
void toString(void delegate(const(C)[]) sink, FormatSpec!C fmt)
void toString(void delegate(const(C)[]) sink)

Converts current value to string, passing it to the given sink using the specified format.

toString
string toString(FormatSpec!C fmt)

Converts current value to string according to the format specification

toString
string toString()

Converts current value to string in floating point or scientific notation,which one is shorter.

toString
string toString(const(C)[] fmt)

Converts current value to string according to the format specification
