The exact value could never be expressed as a number, as pi is an irrational number. The integer value would be: 31415926535897932384626433832795028841 If you want a slightly more accurate value: 31415926535897932384626433832795028841.9716939937510582097494 If you want an exact value: ∞ (∫e-x² dx)2 × 1038 -∞
When the exact number is not required, only a ball park figure or an order of magnitude. This could be forced upon you when you do not have exact values for the two quantities involved.

carbon resistors of standard values are manufactured because other values can be obtained by series and parallel combination of standard values. Moreover even standard values do not offer exact Resistance's will have tolerance
