WP34S handheld SLV, ∫ speed

Solve exits if the last two approximations are sufficiently close, or if the function result is very close to zero. You may force a zero result by rounding the result at the end of your function routine. The 34s has a some special rounding functions that will help here. For instance, RDP 04 rounds the result to 4 decimal places. There is no need to change the display format.

Integrate, on the other hand, quits its iteration as soon as the two last approximations agree when rounded to display precision (!). This means: if you set SCI 4 the result is returned as soon as the result can be considered correct in five significant digits (that's what SCI 4 displays).
