Call the &96DA routine to get the Float value.
Jump to &A9D4 with A = &38 to multiply the FWA by the Floating-Point
constant at location &BF38 in the Floating-Point constant table.
The constant value at &BF38 is 0.0174532925. This value is Pi / 180, or Degree. Multiplying
the Float value by this constant gives the value in Radians.
