squashing two commits together ---- Commit 1 ---- improve calculation accuracy Allow using float point arguments to avoid truncation. Test: Add (4.9, 4.9) should return 10. Signed-off-by: Sergii Piatakov <sergii.piatakov@globallogic.com> ---- Commit 2 ---- fix truncation error To convert float to integer the truncation is performed, but the rounding is expected. Test: Add (4.9, 4.9) should return 10.
