this bit:
" ${eval:<string>} and ${eval10:<string>}
" These items supports simple arithmetic and bitwise logical
" operations in expansion strings. The string (after expansion) must be
" a conventional arithmetic expression, but it is limited to basic
" arithmetic operators, bitwise logical operators, and parentheses.

you mean like like where it says:
${eval:(1+2)*3} yields 9
and
${eval:-(~255&0x1234)} yields -4608
the exim documentation doesn't waste many words, some parts needed
several readings before I understood them.
