To convert the integer to float, use the float () function in Python. Extract the mantissa from the mantissa field, and restore the Use DECIMAL with a larger scale than you need, and format it to the number of decimal places you need now (in your queries, or create a view, or create a computed column). If the exponent has minimum value (all zero), special rules for denormalized values are followed. The result is then treated as a value of the destination type. Floating point examples.pdf - Example 1: What is the decimal equivalent With this converter you can convert a decimal number into a floating point number (IEEE) and vice versa. svg viewer The fractional part is first converted into a decimal by summing all the 2 - n 2^{-n}. Thanks! Based on your expected output for the square root of 3, it seems that you really just want to truncate or extend the square root output to 4 decimal places (rather than round up or down). Precision may be negative. This is effectively identical to the values above, with a factor of two shifted between exponent and mantissa. Jordan's line about intimate parties in The Great Gatsby?

As specify in comment of the @Dan answer, his answer was not working as expected for some values. Q-format Converter & Calculator - GitHub Pages The mantissa (also known as significand or fraction) is stored in bits 1-23. Hexadecimal Representation: Rounding from 64-bit to 32-bit representation uses the IEEE-754 round-to-nearest-value mode. Floating point calculator 32 bit - Math Topics Converting float to decimal - Math Methods It is based on the big integer based algorithm I describe in my article Correct Decimal To Floating-Point Using Big Integers. JSON is used as data interchange format and all the code will do is convert float to string and then load that string as Decimal.

If you store more info than you need now, you can always expose more later. So if you have a number that could have as many as 15 decimal places you need to format as Decimal("%.15f" % my_float), which will give you garbage at the 15th decimal place if you also have any significant digits before decimal (Decimal("%.15f" % 100000.3) == Decimal('100000.300000000002910')). It is possible though to round that value with a reasonable precision and convert it into Decimal.
