# Continued fraction of constant (1)

## Calculates the continued fraction expansion of constant number with n terms. a0/(b0+a1/(b1+a2/(b2+...

 $\normal f={\large\frac{a_0}{b_0+{\large\frac{a_1}{b_1+{\large\frac{a_2}{b_2+...}}}}}}\\$
a0
 the 1st term numerator
b0
 the 1st term denominator
an
 the n-th term numerator
bn
 the n-th term denominator
