NAME
    digit - digit at specified position in a decimal representation

SYNOPSIS
    digit(x, y)

TYPES
    x		real
    y		integer

    return	integer

DESCRIPTION
    By extending the digits on the left, and if necessary, the digits
    on the right, by infinite strings of zeros, abs(x) may be considered
    to have the decimal representation:

		... d_2 d_1 d_0.d_-1 d_-2 ...

    digit(x,y) then returns the digit d_y.

EXAMPLE
    > x = 12.34
    > print digit(x,2), digit(x,1), digit(x,0), digit(x,-1), digit(x,-2)
    0 1 2 3 4

    > x = 10/7
    > print digit(x,1), digit(x,0), digit(x,-1), digit(x,-2), digit(x,-3)
    0 1 4 2 8

LIMITS
    If x is not an integer, y > -2^31

LINK LIBRARY
    long qdigit(NUMBER *x, long y)
