 From help, it says

"in effect takes all digits to the left of the decimal point and drops the others."

Since 100*1.15 = 114.99999999999999

Then all digits to the left of the decimal point is 114

If you had instead wrote

IntegerPart[100*115/100] then you would have obtained 115, but
you'r working with floating points numbers.
