    cfappr - approximate a value using continued fractions

SYNOPSIS
    cfappr(x [,acc])

TYPES
    x		real
    acc		real

    return	real

DESCRIPTION
    Approximate x by using continued fractions until the approximation
    error is less than acc.  By default, acc is epsilon().

EXAMPLE
    > print cfappr(1.2345678), cfappr(1.2345678, 0.1), cfappr(1.2345678, 0.01)
    1.2345678 1.25 ~1.23076923076923076923

LIMITS
    acc > 0

LIBRARY
