Converts a Decimal value to SpannerNumeric,

Parameters
NameDescription
valueDecimal

The value to convert

lossOfPrecisionHandlingLossOfPrecisionHandling

How to handle values with signficant digits that would be lost by the conversion.

Returns
TypeDescription
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
TypeDescription
Int32

A hash code for this value.

Overrides

Parse(String)

public static SpannerNumeric Parse(string text)

Parses a textual representation as a SpannerNumeric.

Parameter
NameDescription
textString

The text to parse. Must not be null.

Returns
TypeDescription
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
TypeDescription
FormatException

The value could not be parsed as a SpannerNumeric.

ToDecimal(LossOfPrecisionHandling)

public decimal ToDecimal(LossOfPrecisionHandling lossOfPrecisionHandling)

Converts this value to SpannerNumeric,

Parameter
NameDescription
lossOfPrecisionHandlingLossOfPrecisionHandling

How to handle values with signficant digits that would be lost by the conversion.

Returns
TypeDescription
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
TypeDescription
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
TypeDescription
String

A canonical string representation of this value.

Overrides

TryParse(String, out SpannerNumeric)

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

Attempts to parse a textual representation of a SpannerNumeric value.

Parameters
NameDescription
textString

The text to parse. Must not be null.

valueSpannerNumeric

The parsed value, or 0 on failure.

Returns
TypeDescription
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
NameDescription
lhsSpannerNumeric

The first value to add.

rhsSpannerNumeric

The second value to add.

Returns
TypeDescription
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
NameDescription
lhsSpannerNumeric

The first value to compare.

rhsSpannerNumeric

The second value to compare.

Returns
TypeDescription
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
NameDescription
valueSpannerNumeric

The numeric value to convert.

Returns
TypeDescription
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
NameDescription
valueDecimal

The decimal value to convert.

Returns
TypeDescription
SpannerNumeric

The result of the conversion.

Parameter
NameDescription
valueInt32

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)

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
TypeDescription
ArgumentException

obj is non-null but does not refer to an instance of SpannerNumeric.
