Tables Adapted for Machine Computation

In actuarial and particularly in casualty actuarial work the occasion often arises when it is necessary to make a more or less isolated calculation for which full tables are not available covering the particular function involved. For example, we may have to determine the present value of $12.00 a week for 200 weeks at 31(1/2)% per annum compound interest, and it may be necessary to do this with considerable accuracy; for instance, in order to comply with some statutory or other legal requirement. If we do not have available a table of the present values of such weekly annuities certain, we have to make the calculation from first principles or from the appropriate formula.
