I used the instruction as below to get random uniform number.
But I want to get u(-100,1) .
i write 1.0+ (100.0* uniform(s))

is it correct?

----------------------------------------------------------
inline float uniform(long &s){return float(next(s))/m;}
inline long next(long &s){return s = (a * s + c) % m;}
where
const long m = 714025; const long a = 1366; const long c = 150889;
are one of the three sets of linear congruence generators that satisfy all the requirements for reasonable randomness.

Your uniform function generates floating point numbers from in the range [0, 1) right? (including 0 and excluding 1)

To generate a random number between -100 and 1 you would do
1 - 101 * rand()
