Hello, I have written a function that does not work correctly, because the function is expected to be inaccurate, which is not due to the source code. It also calculates too imprecisely if I choose the floating point model precise.
I have developed a test program that calls this function:
#include <stdio.h>
#include <math.h>
static unsigned short int getDecimalPlaces(double value)
{
unsigned short int result=0;
double currentValue=value>=0.0?value:-value;
currentValue=currentValue-floor(value);
while(currentValue!=0.0)
{
result++;
currentValue*=10;
double floorValue=floor(currentValue);
currentValue-=floorValue;
}
return result;
}
int main(int argc, char *argv[])
{
double value1=99999.999999; //double value with 6 decimal places
unsigned int decimalChars=getDecimalPlaces(value1);
printf("%.6f has %u decimal places\n",value1,decimalChars);
return 0;
}
When running the test program, the following appears in the console:
99999.999999 has 36 decimal places
Is there a way to configure Pelles C so that the function getDecimalPlaces works correctly?
