Why not create a random number between 0 and 100, and then divide by 100?

... or in this case between 100 and 150.
I general, if you want a decimal number between X and Y,
(1) Create a random number between 0 and ((Y-X)*100) (assuming X > Y)
(2) Add on X*100
(3) Divide by 100.
So for between 0.01 and 1.00
(X) (Y)
(1) Create a number between 0 and 99.
(2) Add 1 = (X*100) to it
(3) Divide by 100.
And for between 1.00 and 1.50
(X) (Y)
(1) Create a number between 0 and 50
(2) Add 100 (X*100) to it
(3) Divide by 100.
Hope this helps,
Ben.
(BTW I think it works, give it a go)
