Hi all,

I want to pick real numbers randomly from a specific range (0 , 0.2304). Can any one help me to do that?

Thank you

Did you look up rand in the help? It's the very first example.

rand*0.2304

For a general case (a,b)

a=0.12
b=0.45
out=a+(b-a)*rand;

Thanks for the answer. However, is there a way to reduce the generated number to 4 float point numbers?

for example:

0.187712337344988 --> 0.1877

Thanks again!

out4decimalPlaces = round(out * 10000)/10000
