Error description

  • The DXL Function intOf(real) provides incorrect output for
    values in range -1.0 ? x ?= -0.5
    For numbers in this range, the result is 0 instead of -1.
    
    Consider the following example:
    ------------------------------------
    real x = -0.9
    print intOf(x)
    
    The output produced is 0 instead of -1.
    
    More examples:
    ==================================
    x                        result
    -0.5                    0           (should be -1)
    -0.7                    0           (should be -1)
    -0.99                   0           (should be -1)
    ==================================

    The DXL Function intOf(real) provides incorrect output for
    values in range -1.0 ? x ?= -0.5. The output produced is 0
    instead of -1
    

Problem conclusion

  • The function which implements the perm intOf(real) is
    incorrect. Since existing customers are accustomed to the
    behavior of perm, a new perm is introduced to correct the
    issue. "RoundtoNearestInt" perm is introduced which will
    behave same as intOf except for the range -1.0 ? x ?= -0.5,
    wherein the real value will be rounded to nearest as
    expected. intOf() perm remains unchanged.
