Floating-Point Math Instructions Example STL Explanation OPN DB10 L ID10 //Load the value of ID10 into ACCU 1. L MD14 //Load the value of ACCU 1 into ACCU 2. Load the value of MD14 into ACCU 1. -R //Subtract ACCU 1 from ACCU 2; store the result in ACCU 1. T DBD25 //The content of ACCU 1 (result) is transferred to DBD25 in DB10.

Floating-Point Math Instructions 8.3.3 *R Multiply ACCU 1 and ACCU 2 as Floating-Point Numbers (32-Bit IEEE-FP) Format *R Description of instruction Result Status word Example *R (multiply 32-bit IEEE floating-point numbers) multiplies the contents of accumulator 2 by the contents of accumulator 1. The contents of accumulator 1 and accumulator 2 are interpreted as 32-bit IEEE floating-point numbers. The result is stored in accumulator 1 as a 32-bit IEEE floating-point number. The instruction is executed without regard to, and without affecting, the RLO. The status bits CC 1, CC 0, OS, and OV are set as a result of the instruction. The contents of accumulator 2 remain unchanged for CPUs with two ACCUs. The contents of accumulator 3 are copied into accumulator 2, and the contents of accumulator 4 are copied into accumulator 3 for CPUs with four ACCUs. The contents of accumulator 4 remain unchanged. The result in ACCU 1 is CC 1 CC 0 OV OS Note +qNaN 1 1 1 1 +infinite 1 0 1 1 Overflow +normalized 1 0 0 - +denormalized 0 0 1 1 Underflow +zero 0 0 0 - -zero 0 0 0 - -denormalized 0 0 1 1 Underflow -normalized 0 1 0 - -infinite 0 1 1 1 Overflow -qNaN 1 1 1 1 BR CC 1 CC 0 OV OS OR STA RLO /FC writes: - x x x x - - - - STL Explanation OPN DB10 L ID10 //Load the value of ID10 into ACCU 1.
