Converts a Decimal value to SpannerNumeric,

Parameters
Name	Description
`value`	`Decimal` The value to convert
`lossOfPrecisionHandling`	`LossOfPrecisionHandling` How to handle values with signficant digits that would be lost by the conversion.

Returns
Type	Description
`SpannerNumeric`	The converted value.

Remarks

This conversion may silently lose precision, depending on lossOfPrecisionHandling.

GetHashCode()

public override int GetHashCode()

Returns a hash code for this value.

Returns
Type	Description
`System.Int32`	A hash code for this value.

ValueType.GetHashCode()

Parse(String)

public static SpannerNumeric Parse(string text)

Parses a textual representation as a SpannerNumeric.

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

Returns
Type	Description
`SpannerNumeric`	The parsed value.

Remarks

text must be a representation of a decimal value which can be represented by SpannerNumeric, 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 SpannerNumeric.

ToDecimal(LossOfPrecisionHandling)

public decimal ToDecimal(LossOfPrecisionHandling lossOfPrecisionHandling)

Converts this value to Decimal,

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, and only includes as many decimal places as are required to completely represent the value. 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 SpannerNumeric)

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

Attempts to parse a textual representation of a SpannerNumeric value.

Parameters
Name	Description
`text`	`String` The text to parse. Must not be null.
`value`	`SpannerNumeric` 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

Addition(SpannerNumeric, SpannerNumeric)

public static SpannerNumeric operator +(SpannerNumeric lhs, SpannerNumeric rhs)

Returns the result of adding two SpannerNumeric values together.

Parameters
Name	Description
`lhs`	`SpannerNumeric` The first value to add.
`rhs`	`SpannerNumeric` The second value to add.

Returns
Type	Description
`SpannerNumeric`	The result of adding the two values.

Equality(SpannerNumeric, SpannerNumeric)

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

Compares two values for equality.

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

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