print, long(1.0e10) [message #16541]

Hi,

I got different results from the following example on SGI IRIX and PC
Linux:
a = 1.0e10
b = long(a)
print, b ; 2147483647 for IRIX, -2147483648 for Linux

It looks like that IRIX and Linux handle it differently when assigning a
floating value greater (or less) than the boundary of a long integer to
a long variable. Should I always check the range of 'a' before
assigning it to a 'long' variable to make the result consistent on IRIX
and Linux ?

TIA,

Gary
