Treatment Examples
Less than
0.5
The fractional part is truncated. 1.49 → 1
−1.49 → −1
0.5 If the ones digit is an even number, the fractional part
is truncated. If it is an odd number, the value is
rounded up.
1.50 → 2
2.50 → 2
−1.50 → −2
−2.50 → −2
Greater
than 0.5
The fractional part is rounded up. 1.51 → 2
−1.51 → −2
