Name	Description
`decimal128FromBID`	`decimal128FromBID` overloads
`decimal128FromDPD`	`decimal128FromDPD` overloads
`decimal128FromDouble`	Same as the related overload above for `decimal128FromDouble`.
`decimal128FromFloat`	Return a decimal floating-point number converted from the specified `binary`.
`decimal128FromNetwork`	Same as the overload taking `Decimal64`.
`decimal128ToBID`	DEPRECATED: Use `decimalToBID` instead.
`decimal128ToDPD`	DEPRECATED: Use `decimalToDPD` instead.
`decimal128ToDouble`	DEPRECATED: Use `deciamalToDouble` instead.
`decimal128ToFloat`	DEPRECATED: Use `deciamalToFloat` instead.
`decimal128ToNetwork`	Same as the related overload above for `decimal128ToNetwork`.
`decimal32FromBID`	Same as the related overload above for `decimal32FromBID`.
`decimal32FromDPD`	Same as the related overload above for `decimal32FromDPD`.
`decimal32FromDouble`	Same as the related overload above for `decimal32FromDouble`.
`decimal32FromFloat`	DEPRECATED: Use `decimalFromFloat` instead.
`decimal32FromNetwork`	Same as the related overload above for `decimal32FromNetwork`.
`decimal32ToBID`	Same as the related overload above for `decimal32ToBID`.
`decimal32ToDPD`	Convert the specified `decimal` to densely packed decimal format in the specified `buffer`.
`decimal32ToDouble`	Same as the related overload above for `decimal32ToDouble`.
`decimal32ToFloat`	Same as the related overload above for `decimal32ToFloat`.
`decimal32ToNetwork`	Same as the related overload above for `decimal32ToNetwork`.
`decimal64FromBID`	`decimal64FromBID` overloads
`decimal64FromDPD`	`decimal64FromDPD` overloads
`decimal64FromDouble`	Same as the related overload above for `decimal64FromDouble`.
`decimal64FromFloat`	DEPRECATED: Use `decimalFromFloat` instead.
`decimal64FromMultiWidthEncoding`	Decode a decimal value in the multi-width encoding format from the specified `buffer` having the specified `size`. Return the decoded value. The behavior is undefined unless `buffer` has at least `size` bytes, and `size` is a valid encoding size in the `multi-width encoding` format.
`decimal64FromMultiWidthEncodingIfValid`	Decode a decimal value in the multi-width encoding format from the specified `buffer` having the specified `size` and store the result into the specified `decimal` parameter. Return 0 on success, and non-zero value otherwise. The behavior is undefined unless `buffer` has at least `size` bytes. Note that this function returns a non-zero value and leaves `decimal` unchanged if `size` is not a valid encoding size of the multi-width encoding format.
`decimal64FromMultiWidthEncodingRaw`	Decode a decimal value in the multi-width encoding format from the specified `buffer` having the specified `size`. Return the decoded value. The behavior is undefined unless `buffer` has at least `size` bytes, `size` is a valid encoding size in the `multi-width encoding` format, and `size <= 5`. Note that this function does not support decoding values requiring a full IEEE network encoding, which is supported by the `decimal64FromMultiWidthEncoding` function.
`decimal64FromNetwork`	Same as the related overload above for `decimal64FromNetwork`.
`decimal64FromVariableWidthEncoding`	Store into the specified `decimal`, the value of `Decimal64` value stored in the variable-width encoding format at the specified `buffer` address. Return the address one past the last byte read from `buffer`. The behavior is undefined unless `buffer` points to a memory area holding a `Decimal64` value encoded in the variable-width encoding format.
`decimal64ToBID`	DEPRECATED: Use `decimalToBID` instead.
`decimal64ToDPD`	DEPRECATED: Use `decimalToDPD` instead.
`decimal64ToDouble`	Same as the related overload above for `decimal64ToDouble`.
`decimal64ToFloat`	DEPRECATED: Use `decimalToFloat` instead.
`decimal64ToMultiWidthEncoding`	Store the specified `decimal`, in the multi-width encoding format, into the specified `buffer` and return the number of bytes used by the encoding. The behavior is undefined unless `buffer` points to a memory area with enough room to hold the encode value (which has a maximum size of 8 bytes).
`decimal64ToMultiWidthEncodingRaw`	If the specified `decimal` can be encoded in 5 or fewer bytes of the multi-width encoding format, then store `decimal` into the specified `buffer` in that format, and return the number of bytes written to `buffer`. Otherwise, return 0. The behavior is undefined unless `buffer` points to a memory area having at least 5 bytes. Note that this function does not supporting encoding values requiring a full IEEE network encoding, which is supported by the `decimal64ToMultiWidthEncoding` function.
`decimal64ToNetwork`	Same as the related overload above for `decimal64ToNetwork`.
`decimal64ToVariableWidthEncoding`	Store the specified `decimal`, in the variable-width encoding format, into the specified `buffer` and return the address one past the last byte written into the `buffer`. The behavior is undefined unless `buffer` points to a memory area with enough room to hold the encoded value (which has a maximum size of 9 bytes).
`decimalFromBID`	`decimalFromBID` overloads
`decimalFromDPD`	`decimalFromDPD` overloads
`decimalFromNetwork`	`decimalFromNetwork` overloads
`decimalToBID`	`decimalToBID` overloads
`decimalToDPD`	`decimalToDPD` overloads
`decimalToDouble`	`decimalToDouble` overloads
`decimalToFloat`	`decimalToFloat` overloads
`decimalToNetwork`	`decimalToNetwork` overloads
`isValidMultiWidthSize`	Return `true` if the specified `size` is a valid encoding size in the multi-width encoding format, and `false` otherwise. Note that valid encoding sizes are 1, 2, 3, 4, 5 and 8 bytes.
