Assembly

Google.Cloud.Spanner.V1.dll

Properties

MaxValue

public static PgNumeric MaxValue { get; }

The maximum valid value for PgNumeric, equal to BigInteger.Pow(10, 147455) - 1

Property Value
Type Description
PgNumeric

MinValue

public static PgNumeric MinValue { get; }

The minimum valid value for PgNumeric, equal to -(BigInteger.Pow(10, 147455) - 1)

Property Value
Type Description
PgNumeric

NaN

public static PgNumeric NaN { get; }

NaN (Not a number) represented as a PgNumeric.

Property Value
Type Description
PgNumeric

public static PgNumeric Zero { get; }

Zero represented as a PgNumeric. This is the default value for the type.

Property Value
Type Description
PgNumeric

Methods

CompareTo(PgNumeric)

public int CompareTo(PgNumeric other)
Parameter
Name Description
other PgNumeric
Returns
Type Description
int

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 int GetHashCode()
Returns
Type Description
int
Overrides

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 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 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

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
bool

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

operator ==(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
bool

true if the two arguments are equal; false otherwise.

explicit operator decimal(PgNumeric)

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 operator PgNumeric(decimal)

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 operator PgNumeric(int)

public static implicit operator PgNumeric(int value)

Implicit conversion from int to PgNumeric.

Parameter
Name Description
value int

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 operator PgNumeric(long)

public static implicit operator PgNumeric(long value)

Implicit conversion from long to PgNumeric.

Parameter
Name Description
value long

The integer value to convert.

Returns
Type Description
PgNumeric

The result of the conversion.

implicit operator PgNumeric(ulong)

public static implicit operator PgNumeric(ulong value)

Implicit conversion from ulong to PgNumeric.

Parameter
Name Description
value ulong

The integer value to convert.

Returns
Type Description
PgNumeric

The result of the conversion.

operator !=(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
bool

false if the two arguments are equal; true otherwise.
