Has anyone any idea where I can get a double precision maths library which will work with the Keil C51 compiler.
Hello Dave Have never used the forum before, but I have been driven here by the same need... my project required greater precision than 'float' & I have discovered the hard way that the Keil tools (otherwise very good) ignore the 'double' declaration. You can get a double precision maths library that Keil claim will do the job... it's called GoFast from microdigital (see http://www.smxinfo.com) but it costs around $5,000. I cannot justify the cost as all I need is the four basic functions (+ - / and *). I have had a quick look at the problem & it seems this could be done as C functions (using a union to create the data type & writing functions to do the maths) - if this is all you need, do you want to collaborate on writing & testing these?

Can you still buy those 8087 maths co-processors...?
Hello Andy I am new to using forums, so not sure if I am supposed to answer this or was it for the originator - anyway... not sure about availability of 8087s, but in my case the hardware is fixed so I will work towards a firmware solution. thanks - Paul
it was just a nutty idea!
