A9CF LOG

Submitted by Steve Fewell

Description:

Call the &A746 routine to get the Float value and obtain the result calculation for LN.
Jump to &A9A3 with A = &42 and Y = &BF to multiply the FWA by the Floating-Point
constant at location &BF42 in the Floating-Point constant table.
The constant value at &BF42 is 0.434294482. This value is 1/Log(10). Multiplying the LN result
by this value gives the LOG result.
