Posted on May 17, 2011 at 15:06 We have 2 issues during using COSMIC Compiler 4.3.1 16k Limit version and STVD 4.1.3, R-Link.
First, we don’t have functional value through using Local Variable, when we use as above it shows different value on long_var.
void main(void)
{
long long_var = 0;
float float_var = 0;
long_var = 533485489;
float_var = (float)long_var;
while (1)
{
}
}

Second, Type Casting problem.
long long_var = 533485489;
float float_var = 0;
void main(void)
{
float_var = (float)long_var;
while (1)
{
}
}
It showed wrong value on float_var as it was inserted Type Casting after we declared global variable,

however, it goes properly in main function as follows.
long long_var;
float float_var = 0;
void main(void)
{
long_var = 533485489;
float_var = (float)long_var;
while (1)
{
}
}

We think it has a problem, isn’t it?
