In r0110">[11], Hickerson made an explicit formula for Dedekind sums trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si1.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=a793f7facdb680f1d93c110e62574a92" title="Click to view the MathML source">s(p,q) in terms of the continued fraction of trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si2.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=c754417fa40160ef3561c82ad5e61478" title="Click to view the MathML source">p/q. We develop analogous formula for generalized Dedekind sums trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si3.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=50921a92e992d9bcb46d77112310dc01" title="Click to view the MathML source">s_i,j(p,q) defined in association with the trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si4.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=6d8bba80a3ff6f6fa5cbf0fd6f7131e9" title="Click to view the MathML source">xⁱy^j$x^i{y}^j$-coefficient of the Todd power series of the lattice cone in trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si5.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=a6e0cd47c5e9badb8a166515fc840d6b" title="Click to view the MathML source">R² generated by trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si6.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=92f11dee46d081ca88d5b5d14cd7c151" title="Click to view the MathML source">(1,0) and trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si7.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=3481483978028da6fd62d31f9d298748" title="Click to view the MathML source">(p,q). The formula generalizes Hickerson's original one and reduces to Hickerson's for trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si8.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=956405bad31eb5d3a361ec5075979e01" title="Click to view the MathML source">i=j=1$i=j=1$. In the formula, generalized Dedekind sums are divided into two parts: the integral trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si9.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=099c6f0e102a6cedc9ffbf32a46641bb"> and the fractional trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si10.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=d90ac1223f8bb67d181b25c20727c386">. We apply the formula to Siegel's formula for partial zeta values at a negative integer and obtain a new expression which involves only trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si9.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=099c6f0e102a6cedc9ffbf32a46641bb"> the integral part of generalized Dedekind sums. This formula directly generalizes Meyer's formula for the special value at 0. Using our formula, we present the table of the partial zeta value at trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si11.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=689ff79aa1b80b4bb5d1d0ad78b952b6" title="Click to view the MathML source">s=&minus;1$s=\&<font\; color="red">minus</font>;1$ and &minus;2 in more explicit form. Finally, we present another application on the equidistribution property of the fractional parts of the graph trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si12.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=02df000922d3a943c32a4fa5535f840f"> for a certain integer trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si13.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=285c25c2919bc817ce00b24b2077146a" title="Click to view the MathML source">R_i+j$R_{i+j}$ depending on trieve&_eid=1-s2.0-S0022314X16301548&_mathId=si14.gif&_user=111111111&_pii=S0022314X16301548&_rdoc=1&_issn=0022314X&md5=feebb1991c9eb9545515f1bc4b33537f" title="Click to view the MathML source">i+j$i+j$.
