otp.Operation.round#

Operation.round(precision=0)#

Rounds input column with specified precision.

Rounding otp.nan returns NaN and rounding otp.inf returns Infinity.

For values that are exactly half-way between two integers (when the fraction part of value is exactly 0.5), the rounding method used here is upwards, which returns the bigger number. For other rounding methods see otp.math.round function.

Parameters: precision (int) – Number from -12 to 12. Positive precision is precision after the floating point. Negative precision is precision before the floating point.
Return type: Operation

Examples

>>> t = otp.Tick(A=1234.5678)
>>> t['B'] = t['A'].round()
>>> t['C'] = t['A'].round(2)
>>> t['D'] = t['A'].round(-2)
>>> otp.run(t)
