Comparing Single-precision and Double-precision Calculations

• Ladder Program for the

Single-precision Calculation

This example shows the differences in between single-precision and double-

precision calculations when the following vector expressed in polar coordi-

nates is converted to rectangular coordinates A (x,y).

In this example, the 4-digit BCD angle ( , in degrees) is read from D00000

and the 4-digit BCD distance (r) is read from D01000.

A (x, y) = A (rcos , rsin )
