I get different results depending on the orientation of the phone. When the result has more characters than can be displayed, it truncates the result.
With the phone oriented with the short side up. 45,000,000 * 50 incorrectly displays 225,000,000
With the wide side up the same calculation correctly displays 2,250,000,000
Narrow end up: 123456789 * 10 = 123456789
Wide side up: 123456789 * 10 = 1234567890
