RE: lambertw, all branches
In one of your posts, you wrote:
">>> a = -pi/2 >>> W(a, 0, True) (0.375191803678016 + 1.59508875325509j) (0.0128176527641888 + 1.58759064221342j) (-5.58573510823744e-5 + 1.57084664181356j) (6.00809277877961e-10 + 1.57079632603836j) (5.72587285769658e-17 + 1.5707963267949j) (1.30059124689582e-17 + 1.5707963267949j)" Shouldn't the correct answer rather be 0+i×PI/2? Taking the first digits of PI, ie not the 'exact full form', W0(-1.57079632679489661923132169163975144209858469968755291048) -2.78783334301039861107336040858316822982734956396028 × 10^-63 +1.5707963267948966192313216916397514420985846996875529104 i With the exact form, with "full possible digits", real part —> 0. |
