C library macro - ERANGE
C standard library - <errno.h>
description
Occurrence C library macroERANGE represents a range of error, it is out of range in the input parameters defined by mathematical functions when, errno is set to ERANGE.
statement
Here is the ERANGE macro statement.
#define ERANGE some_value
parameter
- NA
return value
- NA
Examples
The following example demonstrates the usage of the macro ERANGE.
#include <stdio.h>
#include <errno.h>
#include <math.h>
int main()
{
double x;
double value;
x = 1.000000;
value = log(x);
if( errno == ERANGE )
{
printf("Log(%f) is out of range\n", x);
}
else
{
printf("Log(%f) = %f\n", x, value);
}
x = 0.000000;
value = log(x);
if( errno == ERANGE )
{
printf("Log(%f) is out of range\n" x);
}
else
{
printf("Log(%f) = %f\n", x, value);
}
return 0;
}
Let's compile and run the above program, which will result in the following:
Log(1.000000) = 1.609438 Log(0.000000) is out of range
