Figure 5–20. Flowchart for Floating-Point to Integer Conversion by FIX Instruction
Test for special cases of α ( exp)
α
( exp) > 30
α
( exp) in range
rs = 31 –
α
( exp)
Overflow Shift
If α ( man) > 0,
c = most positive integer
If
α
( man) < 0,
c = most negative integer
c = α ( man) > > rs
Set c to final result
α
c = fix( α )
