In other words....by Solitaire (no login)
The result of the first equation came out to no more than 7 digits after the decimal so it could display as is. The result of the second equation was more than 7 digits so it reverted to scientific notation.
If you were to declare your variables as type DOUBLE (using # instead of !) the first result should still be the same, but the second may or may not display in scientific notation depending on whether or not the number of digits after the decimal was more or less than (or equal to) 15.
