does anyone know of a list with the values of things like sine, cosine, & inverse hyperbolic tangent to several hundred deciamls? im having trouble finding a list and i need one to test the accuracy of my program

inverse hyperbolic tangent? O.o

sry, no idea...
I bet, if you really need several hundred decimals, it wouldn't be enough to use a simple calculator? lol

you can try to use the XP-powertoy-calculator..... there, you cah crank up the accuracy to 512 bit! O.o

- that might help, although it might also be some work to type in every single value...
I guess, you wont need it, but it also can calc with i...

damn, I hate it for not being available for 64 bit xp

didnt no powertoys could change acuracy, ill have to try that.

Ive implemented my own version of bigdeciaml class in java, so that it can do all the math types to any arbitrary precision. so i need to make sure its acurate

cool

you can choose (if I remember correctly, as I don't have it anymore) between 16 32 64 128 256 and 512 bit and degree radiant and new degree (gon) and you have all the trigonometric functions avilable + i values

You could use them to calculate pi, you can find that to millions of places.

i know, precomputed lists are easier though, cause i can just batch compare all of my results with a list and its easy

im gona go try powertoys when i get home
