Godot 3.2.3 official from steam
Win10 x64 NVIDIA RTX 2070 GLES2:
*asin(1.571) calculation provide result 1.#QO expected 177.95 :

run code
var center=Vector2(0,0)
var dd=Vector2(0,5)
var dp=Vector2(-0.313,-8.746)
var disdd=center.distance_to(dd) #5
var disdp=center.distance_to(dp) #8.751
var disdddpdiff=dd.distance_to(dp) #13.749
var div=disdddpdiff/disdp #1.571
var angle=asin(div) .#QO expected 177.95
print(angle)

Screenshots attached

asin() parameter must be between -1 and 1 and the return value is in radian (between -PI/2 and PI/2) not in degrees.

Sorry yes my bad value must be in range . I was thinking it related to look_at have no visible effect in my script
