22 ENTER 783 ENTER 56 GSB A f Re<=>Im ->

HP-15C:

3.536885643-05

JRPN 15C:

3.536885811-05

This is equivalent to

783 ENTER 785 ÷ g COS⁻¹ 22 × COS

Both the HP-15C and JRPN 15C return the same result in DEG mode, 3.536927182-05. In RAD mode they differ slightly:

HP-15C:

3.536879499-05

JRPN 15C:

3.536879489-05

The exact 10-digit result is 3.536890463e-5.

Best regards,
