SQL Server DEC2OCT function


 
Updated: 27 August 2010

Use DEC2OCT to convert a decimal number to octal.
Syntax
SELECT [wctEngineering].[wct].[DEC2OCT] (
   <@Number, float,>
 ,<@Places, float,>)
Arguments
@Number
is the decimal integer you want to convert. If @Number is negative, valid @Places values are ignored and DEC2OCT returns a 10-character (30-bit) octal number in which the most significant bit is the sign bit. The remaining 29 bits are magnitude bits. Negative numbers are represented using two's-complement notation. @Number is an expression of type float or of a type that can be implicitly converted to float
@Places
The number of characters to use. If @Places is NULL, DEC2OCT uses the minimum number of characters necessary. @Places is useful for padding the return value with leading 0s (zeros). @Places is an expression of type float or of a type that can be implicitly converted to float. 
Return Types
varchar(4000)
Remarks
·         If @Number is less than -536,870,912 or @Number is greater than 536,870,911, DEC2OCT returns an error.
·         If @Number is negative, DEC2OCT ignores places and returns a 10-character octal number.
·         @Places is truncated to zero decimal places.
