It is implemented with arbitrary-precision arithmetic, so its conversions are correctly rounded. The Visual Basic functions are designed for optimal . Convert from any base, to any base (binary, hexadecimal, even roman numerals!) a 32 bit area in There are some situations where float makes sense, but 99% of the time what they should have used was decimal. This is the format in which almost all CPUs represent non-integer numbers. Step 2: Starting with the least significant digit (LSB - the rightmost one), multiply the digit by the value of the position. My problem is that due to the nature of float, and the way conversions are done, simply casting the float may make it appear to be the wrong number to my users. If the resulting integral value is outside the range of the destination type, an OverflowException is thrown. The SQL format model used to parse the input expr and return.
