NAME
    btrunc - truncate a value to a number of binary places

SYNOPSIS
    btrunc(x [,j])

TYPES
    x		real
    j		int

    return	real

DESCRIPTION
    Truncate x to j binary places.  If j is omitted, 0 places is assumed.
    Specifying zero places makes the result identical to int().

    Truncation of a non-integer prodcues values nearer to zero.

EXAMPLE
    > print btrunc(pi()), btrunc(pi(), 10)
    3 3.140625

    > print btrunc(3.3), btrunc(3.7), btrunc(3.3, 2), btrunc(3.7, 2)
    3 3 3.25 3.5

    > print btrunc(-3.3), btrunc(-3.7), btrunc(-3.3, 2), btrunc(-3.7, 2)
    -3 -3 -3.25 -3.5

LIMITS
    0 <= j < 2^31

LIBRARY
    NUMBER *qbtrunc(NUMBER *x, *j)
