Methods

CompareTo(SpannerNumeric)

public int CompareTo(SpannerNumeric other)

Compares this value with other.

Parameter
Name	Description
other	SpannerNumeric The value to compare with this one

Returns
Type	Description
Int32	A negative integer if this value is less than other; a positive integer if it's greater than other; zero if they're equal.

FromDecimal(Decimal, LossOfPrecisionHandling)

public static SpannerNumeric FromDecimal(decimal value, LossOfPrecisionHandling lossOfPrecisionHandling)

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
Int32	A hash code for this value.

Overrides

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 SpannerNumeric,

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.

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

Explicit(SpannerNumeric to Decimal)

public static explicit operator decimal (SpannerNumeric value)

Explicit conversion from SpannerNumeric to Decimal.

Parameter
Name	Description
value	SpannerNumeric 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.

public static explicit operator SpannerNumeric(decimal value)

Explicit conversion from Decimal to SpannerNumeric.

Parameter
Name	Description
value	Decimal The decimal value to convert.

Returns
Type	Description
SpannerNumeric	The result of the conversion.

Implicit conversion from Int32 to SpannerNumeric.

Parameter
Name	Description
value	Int32 The integer value to convert.

Returns
Type	Description
SpannerNumeric	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 SpannerNumeric)

public static implicit operator SpannerNumeric(long value)

Implicit conversion from Int64 to SpannerNumeric.

Parameter
Name	Description
value	Int64 The integer value to convert.

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 SpannerNumeric.
