public static readonly PgNumeric NaN { get; }

NaN (Not a number) represented as a PgNumeric.

Methods

CompareTo(PgNumeric)

public readonly int CompareTo(PgNumeric other)

Parameter
Name	Description
`other`	`PgNumeric`

Returns
Type	Description
`Int32`

FromDecimal(Decimal)

public static PgNumeric FromDecimal(decimal value)

Converts a Decimal value to PgNumeric,

Parameter
Name	Description
`value`	`Decimal` The value to convert

Returns
Type	Description
`PgNumeric`	The converted value.

GetHashCode()

public override readonly int GetHashCode()

Returns
Type	Description
`Int32`

Overrides

ValueType.GetHashCode()

Parse(String)

public static PgNumeric Parse(string text)

Parses a textual representation as a PgNumeric.

Parameter
Name	Description
`text`	`String` The text to parse. Must not be null.

Returns
Type	Description
`PgNumeric`	The parsed value.

Remarks

text must be a representation of a decimal value which can be represented by PgNumeric, using "." as a decimal place where one is specified, and a leading "-" for negative values. Leading zeroes and insignificant trailing digits are permitted.

Exceptions
Type	Description
`FormatException`	The value could not be parsed as a PgNumeric.

ToDecimal(LossOfPrecisionHandling)

public readonly decimal ToDecimal(LossOfPrecisionHandling lossOfPrecisionHandling)

Converts this value to PgNumeric,

Parameter
Name	Description
`lossOfPrecisionHandling`	`LossOfPrecisionHandling` How to handle values with signficant digits that would be lost by the conversion.

Returns
Type	Description
`Decimal`	The converted value.

Remarks

This conversion may silently lose precision, depending on lossOfPrecisionHandling, but will always throw OverflowException if value is out of the range of Decimal.

Exceptions
Type	Description
`OverflowException`	This value is outside the range of Decimal.

ToString()

public override readonly string ToString()

Returns a canonical string representation of this value. This always uses "." as a decimal point. If the value is between -1 and 1 exclusive, a "0" character is included before the decimal point.

Returns
Type	Description
`String`	A canonical string representation of this value.

Overrides

ValueType.ToString()

TryParse(String, out PgNumeric)

public static bool TryParse(string text, out PgNumeric value)

Attempts to parse a textual representation of a PgNumeric value.

Parameters
Name	Description
`text`	`String` The text to parse. Must not be null.
`value`	`PgNumeric` The parsed value, or 0 on failure.

Returns
Type	Description
`Boolean`	`true` if `text` was parsed successfully; `false` otherwise.

Remarks

See Parse(String) for format details. This method will return true if and only if Parse(String) would return without an exception.

Operators

Equality(PgNumeric, PgNumeric)

public static bool operator ==(PgNumeric lhs, PgNumeric rhs)

Compares two values for equality.

Parameters
Name	Description
`lhs`	`PgNumeric` The first value to compare.
`rhs`	`PgNumeric` The second value to compare.

Returns
Type	Description
`Boolean`	`true` if the two arguments are equal; `false` otherwise.

Explicit(PgNumeric to Decimal)

public static explicit operator decimal (PgNumeric value)

Explicit conversion from PgNumeric to Decimal.

Parameter
Name	Description
`value`	`PgNumeric` The numeric value to convert.

Returns
Type	Description
`Decimal`	The result of the conversion.

Remarks

This conversion may silently lose precision, but will throw OverflowException if the value is out of range of Decimal. Use ToDecimal(LossOfPrecisionHandling) passing in Throw for the second argument to avoid any information loss.

Implicit(Decimal to PgNumeric)

public static implicit operator PgNumeric(decimal value)

Implicit conversion from Decimal to PgNumeric.

Parameter
Name	Description
`value`	`Decimal` The decimal value to convert.

Returns
Type	Description
`PgNumeric`	The result of the conversion.

Implicit(Int32 to PgNumeric)

public static implicit operator PgNumeric(int value)

Implicit conversion from Int32 to PgNumeric.

Parameter
Name	Description
`value`	`Int32` The integer value to convert.

Returns
Type	Description
`PgNumeric`	The result of the conversion.

Remarks

This conversion exists to avoid ambiguity between the 64-bit conversions when using an integer literal.

Implicit(Int64 to PgNumeric)

public static implicit operator PgNumeric(long value)

Implicit conversion from Int64 to PgNumeric.

Parameter
Name	Description
`value`	`Int64` The integer value to convert.

Returns
Type	Description
`PgNumeric`	The result of the conversion.

Implicit(UInt64 to PgNumeric)

public static implicit operator PgNumeric(ulong value)

Implicit conversion from UInt64 to PgNumeric.

Parameter
Name	Description
`value`	`UInt64` The integer value to convert.

Returns
Type	Description
`PgNumeric`	The result of the conversion.

Inequality(PgNumeric, PgNumeric)

public static bool operator !=(PgNumeric lhs, PgNumeric rhs)

Compares two values for inequality.

Parameters
Name	Description
`lhs`	`PgNumeric` The first value to compare.
`rhs`	`PgNumeric` The second value to compare.

Returns
Type	Description
`Boolean`	`false` if the two arguments are equal; `true` otherwise.

Explicit Interface Implementations

IComparable.CompareTo(Object)

readonly int IComparable.CompareTo(object obj)

Implementation of CompareTo(Object) to compare two PgNumeric values.

Parameter
Name	Description
`obj`	`Object` The object to compare this value with.

Returns
Type	Description
`Int32`	The result of comparing this value with `obj`. `obj` is null, this method returns a value greater than 0.

Remarks

This uses explicit interface implementation to avoid it being called accidentally. The generic implementation should usually be preferred.

Exceptions
Type	Description
`ArgumentException`	`obj` is non-null but does not refer to an instance of PgNumeric.
