.IP "\fBterm($n)\fR" 4
.IX Item "term($n)"
Returns the \f(CW$n\fR\-th term of the Fibonacci sequence. The term is computed
using the fast algorithm: \f(CW\*(C`F(n) ~ g^n/sqrt(5)\*(C'\fR, where g is the golden
ratio and ~ means \*(L"take the nearest integer\*(R".
.IP "\fBseries($n)\fR" 4
.IX Item "series($n)"
Computes and returns the first \f(CW$n\fR Fibonacci numbers.
.IP "\fBdecompose($int)\fR" 4
.IX Item "decompose($int)"
Decomposes \f(CW$int\fR into the sum of Fibonacci numbers. Returns the list of
Fibonacci numbers.
.IP "\fBisfibonacci($int)\fR" 4
.IX Item "isfibonacci($int)"
Returns the sequence number of \f(CW$int\fR if it is a Fibonacci number or a
non-true value if it is not.
