[fitsbits] Output array type when BZERO is an integer {External}

[William Pence]

I think the confusion here comes from thinking that BZERO can have an integer value.  This is incorrect because by definition BZERO always has a floating point value even if the decimal point is not explicitly present, and even if the keyword is not actually present in the header.

However, I'm not clear about the data type for the special case where BZERO is an integer. In this case, it appears that BZERO is added first to the integer array before converting it to a floating point array, because BSCALE = 1.0 implies upconversion. Is this correct?
