smoothstep

Returns 0.0 if x <= edge0 and 1.0 if x >= edge1 and performs smooth Hermite interpolation between 0 and 1 when edge0 < x < edge1.

F2 smoothstep(F1 edge0, F1 edge1, F2 x)

1. Returns 0.0 if `x <= edge0` and 1.0 if `x >= edge1` and performs smooth Hermite interpolation between 0 and 1 when `edge0 < x < edge1`.
   Parameters:
   • F1 edge0
   • F1 edge1
   • F2 x
