scaling an object_discrete scale

PROBLEM:
When trying to scale an object (like the sphere in the example below) when i grab the scale tool it jumps by 1s instead of scaling in the decimals.

NOTE: I can still scale in the decimales in my attribute editor.


Here is the sphere I am trying to scale. (img above)


When I try to scale in the Y the sphere jumps instantly from 0.7 to 1.7 instead of increasing with my mouse movement.


When I try to scale in the Z the sphere till jumps from 0.7 to 1.7. (img above)


When I try to scale all part in the X Y and Z it jumps from 0.7 to 1.7 in all of the attributes. (img above)

I think the problem is in the preferences but I don't know what preferences to readjust.

SOLUTION: I had unknowingly had discrete scale turned on. When discrete scale is turned on you can hold 'j' while scaling and scale normal.
