Error with exponential term

Hi everyone,

I do have a question regarding the function of exponential result no showing all the decimal points.

Here is the code I have written: (For Kg1, it only shows "0". But, in kg2, it shows the whole result.) It would be greatly appreciated if anyone has any suggestion. Thank you.

T1=600;
kgo1=0.1;
Eg1=10000;
Rg1=8.314;
Kg1=kgo1*exp(-Eg1/Rg1*T1)
kg2=kgo1*exp(-2.00465)

>> E

Kg1 =

0

kg2 =

0.0135

>>

You could type

format long

before running that code, or use the sprintf command to display the result.

Looks like Kg1 is 0 to within double precision, though.

>> exp(-740)

ans =

    4.199557989650596e-322

>> exp(-750)

ans =

     0
