How to convert Double.POSITIVE_INFINITY to BigDecimal?

Question

I tried BigDecimal.valueOf(Double.POSITIVE_INFINITY), but kept getting NumberFormatException

Thanks

Answer 1

You cannot represent infinity in BigDecimal.

Answer 2

This behavior corresponds to the documented way the valueOf method is supposed to work:

Parameters: val - double to convert to a BigDecimal.

Returns: a BigDecimal whose value is equal to or approximately equal to the value of val.

Throws: NumberFormatException - if val is infinite or NaN.
