Description Teresa Thomas 2007-11-02 15:45:39 UTC 
(fhpd) print float_ 
[0.0]

4.0
(fhpd) print float_ + 1 
[0.0]

0.0
Comment 1 Teresa Thomas 2007-11-15 20:13:14 UTC 
Prints by C test program on i686 - uses sizeof operator:
sizeof float_: 4
sizeof long_: 4
sizeof (long_ + float_): 4

GDB outputs:
(gdb) print sizeof long_
$1 = 4
(gdb) print sizeof float_
$2 = 4
(gdb) print sizeof (long_ + float_)
$3 = 8  [NOTE!]
Comment 2 Teresa Thomas 2008-01-24 19:34:08 UTC 
    Use BigFloatingPoint for arithmetic operations.
