It's accurate to about 5 places past the decimal point, and can handle numbers in the range of approximately -32767.99998 through +32767.99998. A fixed-point variable occupies 4 bytes of storage. > > However, this short program seems to indicate that the FIXED variables now are being treated as integers. :-( > [snip] > Am I misunderstanding the type FIXED or is the a new bug in FB5/FB2C? > I thought this would a month or so ago when I last tried this and other examples. It could never have worked. As a check, I tried your demo in FB4 and the results are the same. To work with Fixed variables you have to convert decimal forms on input/output and use FixXxxxx() functions for math operations other than addition and subtraction. // FixMath.h toolbox fn FixRatio( short numer, short denom ) = Fixed toolbox fn FixRound( Fixed x ) = short toolbox fn Long2Fix( long x ) = Fixed toolbox fn Fix2Long( Fixed x ) = long toolbox fn FixDiv( Fixed x, Fixed y ) = Fixed toolbox fn FixMul( Fixed a, Fixed b ) = Fixed toolbox fn FixATan2( long x, long y ) = Fixed For general programming, the Fixed type became redundant when processors got hardware floating-point.
