Do we have an example that can be referred to convert a Java BigDecimal to OMMReal (mantissa and magnitude) so can be populated in the expression like below:
fieldList.add(EmaFactory.createFieldEntry().real(22, <mantissa>, <magnitude>));
Searched the forum and found one in the question description:
I can't find an example for it. However, you can try this code.
BigDecimal test = new BigDecimal("125.5831200");
fieldList.add( EmaFactory.createFieldEntry().real(25, test.unscaledValue().longValue(), OmmReal.MagnitudeType.EXPONENT_0 - test.scale()));
BigDecimal::unscaledValue() returns a BigInteget whose value is the unscaled value of this BigDecimal. I think it is mantissa of OMMReal.
BigDecimal::unscaledValue() returns the scale of this BigDecimal. We need to convert this value to the OMMReal hint (magnitude).
This is a simple snippet code. It isn't fully tested and doesn't cover all use cases.
