Can anyone answer the two questions below for me? A friend was asking me that. I found the following quote at the indicated URL: URL: http://www.rtlinux.org/~rtlinux/body.shtml "Fixed Point Arithmetic The rt_fixed Kernel-Module implements fixed point arithmetic for use under rt-linux. The intention is to avoid using the FPU in kernel-space and thus implementing a method to do calculations without interfering with linux. The basic approach is to convert double numbers to numbers of type rt_fixed14 before sending them to the rt-linux side of an application." This quote seems to imply that it is a BAD THING to use floating point in real-time applications under RT Linux. This leads to two questions: 1) Do you have to use fixed point arithmetic with RT Linux or can you use floating point arithmetic? 2) If floating point cannot be used, why not? I have several large sections of floating point code that I would like to run in real time without having to rewrite the code to use fixed point arithmetic. --- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] ---- For more information on Real-Time Linux see: http://www.rtlinux.org/~rtlinux/
