Theorem: SciLean.Scalar.toReal_dite (SciLean/Core/Objects/Scalar.lean)

State before:
R : Type u_1
inst✝¹ : RealScalar R
c : Prop
inst✝ : Decidable c
t : c → R
e : ¬c → R
⊢ toReal R (if h : c then t h else e h) = if h : c then toReal R (t h) else toReal R (e h)
Tactic:
if h : c then simp[h] else simp[h]
