Call the &A8BE routine to load the FWA with the Floating-Point constant at
location &BF2E in the Floating-Point constant table.
The constant value at &BF2E is 1.57079633. This value is Pi / 2.
Add 1 to the exponent to multiply this value by 2, this will give Pi as the result.
Exit with the FWA set to Pi (3.14159266).
