#83761 - Keil
Responding to: ???'s previous message
Vijayganesh S said:
Now I need Keil help. I have tried the square root functions in uvision2 but i am getting errors in object source file opening.

Are you using the free evaluation version?
If so, read this: http://www.keil.com/demo/limits.htm

Also, I dont know how much precision we can achieve in 8-bit floating point values.

It's all in the Keil C51 Manual.
Although the 8051 is an 8-bit processor, floating point values are not stored in 8 bits. This is just the first of many reasons why floating point is not a good idea on the 8051!

Try fixed-point instead.

Please give me suggestions or resources for the following.

Start by looking in the Code Library; then use the 'Search' button - it's all been covered before ad nauseam
