• Fractional to Decimal Form.

  - by ThePower

  Hi, there probably isn't an answer to this apart from "Create it yourself", but you never know, there might be some string representation for this. Basically, I would like to display number values as fractional instead of decimal when displaying the values as a string. Instead of a value displaying as: 1.1428571428571428571428571428571 I would prefer it to display as 8/7 Is there any way of doing this without writing the functionality myself? Regards Lloyd

• converting factored number to decimal in MS SQL

  - by LS

  I need to convert a number which gives decimals in factored format in to decimals, i.e. 11.16 is 11.5 in decimal. This is because 16 is in base of 32 and 11.16 should be read as 11+16/32 = 11.5 I get 11.16 as a string and I need to change it to 11.5 as numeric in MS SQL(2005) database. Any shorter way of doing this rather than splitting strings,converting to numerics,maths,convert to string, concatenate and then convert to numeric?
