| version | |
| 2.15 | yet another bugfix in deg(x) and also in dms(x) |
| 2.14 | another bugfix in deg function! |
| 2.13 | bugfix in deg function. |
| 2.12 | added tvm functions, fv(i,n,pmt,pv), pmt(i,n,pv,fv),
rate(n,pmt,pv,fv). also added lnone(x) = ln(x+1) note: tvm functions are the same parameters to those used by excel. |
| 2.11 | fixed crash on exit bug on the T3 (and maybe others). |
| 2.10 | minor bugfix |
| 2.09 | added some humidity functions to library. |
| 2.08 | added ncr & npr (combinations & permutations). |
| 2.07 | fixed a bug with arccos(cos(45)) (degress). |
| 2.06 | improve mod accuracy for large arguments, eg mod(1e120,9)=1 |
| 2.05 | allow +/- key to toggle and enter exponent sign whilst entering a number. |
| 2.04 | added factor(x) function and factorisation button (integer factorisation) |
| 2.03 | added "fractions" button. added jd(yyyy.mmdd) & date(x), date conversions to julian day number and back added elf(k,phi) and ele(k,phi) Legendre elliptic integrals of first and second kinds. |
| 2.02 | mod(x,y) requires 60 digit precision for 30 digit result. added modtwopi(x) accurate for |x| <= 1e130. trig functions use modtwopi for accurate domain reduction. |
| 2.01 | bug fixes for color displays. |
| 2.00 | new interface. |
