According to the manual: before rounding.

M68000PRM, section 3.6.1 (p. 3-28): "At the completion of an arithmetic
operation, the intermediate result is checked to see if it is too small
to be represented as a normalized number in the selected precision. If
so, the underflow (UNFL) bit is set in the FPSR EXC byte."
