a = 5
b# = 10.3

c = a * b#

Is a promoted to 5.0 and then multiplied by b#, OR
Is b# rounded to 10 and multiplied by 5?

The first. Integers are promoted to floats, but only at the last instant before use.

'5 * 2 * 1.5' is calculated as follows:
integer 5 multiplied integer 2, the result converted to a float, then multiplied by 1.5
