Var_dump ("03E-004611" = = "36E-008026"); BOOL (TRUE)
Var_dump (03E-004611, 36E-008026); Float (0) float (0)
Var_dump ("03E-004611" = = = = "36E-008026"); BOOL (FALSE)

A string of numbers that is converted to a number before being compared.
------Solution--------------------
Because E is 10 of the operation "03E-004611" converted into a number of points when the number is infinitely close to 0, 3*pow (10,-4611), up to such a high precision, so it is 0.
