'''Official Name:''' Times2<br />
<br />
'''BCALL Address:''' 4066<br />
<br />
Doubles the floating point number in [[83Plus:RAM:8478|OP1]].<br />
<br />
=== Inputs ===<br />
* OP1 = floating point number<br />
<br />
=== Outputs ===<br />
* OP1 = 2*OP1<br />
* OP2 = original value of OP1<br />
<br />
=== Registers Destroyed ===<br />
* AF, BC, DE, HL<br />
<br />
== Comments ==<br />
This is faster than loading OP2 with 2 and using [[83Plus:BCALLs:4084|FPmult]].<br />
<br />
== Example ==<br />
<nowiki>B_CALL OP1Set3 ;OP1=floating point 3<br />
B_CALL Times2 ;returns with OP1=floating point 6<br />
