Server Differences

The basic behavior of fdiv() is the same across PennMUSH, TinyMUSH, and TinyMUX, however, the usual floating-point differences apply. For example:

On PennMUSH, fdiv(1,1e-9) ==> '1000000000' while fdiv(1,1e-10) ==> '#-1 DIVISION BY ZERO'.
On TinyMUSH, fdiv(1,1e-10) ==> '10000000000' while fdiv(1,1e-130) ==> '9999999999999999366518088823188676468029287122850159299994507296276799832366962053631754981778769796749861527090709766158759755776'
On TinyMUX, fdiv(0,0) ==> 'Ind', fdiv(1,0) ==> '+Inf', fdiv(-1,0) ==> '-Inf', and fdiv(1,1e-130) ==> '9.999999999999999E129'.
RhostMUSH's fdiv() behavior equals that of TinyMUSH.
