is it int or real? 1

[bobo12]

so if we have something like
IALL = 0
ITOT = 0
NTOT = 10
NS = 0
NI = 10
and this is the first time the lhs are actually being used, without define, are these set to doubles or ints?

some user earlier mentioned that lhs if not defined with a type are real. so why does this code contain ints.

 

[bobo12]

plz assume f77

If the identifiers begin with letters between I and N inclusive, then it is an integer, otherwise it is real. Also assume integer division.

 

[bobo12]

oh so all division statements involve int's and no reals
int = int / int; always unless explicit is used?

 

[bobo12]

what about multiplication?
it's kind of strange, what if one really needed to /,* real #'s?

 

[bobo12]

A**2, is same as A^2 and A*A right?
it's just that i am getting an error saying that operator ^ can't be applied to double,int?
i guess i can just use A*A

A**2 in C is pow(A,2). In C ^ means exclusive OR.

Multiplication - same rules as C: it gets promoted to a real.
