Dear all,
I need to do floating point arithmetic in systemc.
My question is if after I do two floating point addition or multiplication, can I call this api(is_inf()) for the sum or product to determine
it is inf or not? The produced results looks correct for me.
Like the following sample code
```c
num1.negative(sign1);
num2.negative(sign2);
num1.exponent(exp1);
num2.exponent(exp2);
num1.mantissa(significand1);
num2.mantissa(significand2);
//the additiion result
result = num1+num2;
cout.precision(23);
cout << result.is_inf() << " " << num1 << " " << num2 << " " << result << endl;
```
The following are my test samples:
The first column is is_inf flag, the second and the third column are the source operands and the last column is the produced result.
```
1 -3.402823466385288598117e+38 -3.402823466385288598117e+38 -inf
0 0.5 -0.20000000298023223876953 0.30000001192092895507812
0 0.5 -9.9999997473787516355515e-05 0.49990001320838928222656
0 0.5 -0.30000001192092895507812 0.19999998807907104492188
0 0.5 100 100.5
0 0.5 2003 2003.5
0 0.5 100000 100000.5
0 0.5 -1000000 -999999.5
```
Any guidance is appreciate.
