Hi all.
using uVision 4, keil compiler.
I'm trying to create a very simple function that takes an argument list, but it seems like when i use parameters of type double, it doesn't work right. I started fiddling around with the double datatype, and maybe i'm doing something wrong, but ...
// double trouble double d = 1234.1234; double* dp = &d; double e = *dp; // e has gibberish, d is fine // float is ok float f = 1234.1234; float* fp = &d; float g = *fp; // g is fine, f is fine // in fact ... float f = 1234.1234; float* fp = &d; double g = *fp; // g has gibberish, f is fine // also ... float f = 1234.1234; double d = (double)f; // d has gibberish(!) // wha... double d = 1234.1234; double e = d; // both d and e have gibberish. // contrast to float d = 1234.1234; float e = d; // both d and e are fine // adding a pointer.. cures it? double d = 1234.1234; double* dp = &d; double e = d; // e has gibberish, d is fine. // more pointers... double d = 1234.1234; double* dp = &d; double e = d; double* ep = &e; // both d and e are fine.
can someone explain what's going on???
