-!!! danger "Undefined behavior for pointers"
+!!! danger "Undefined behavior"
 
     Writing data to the pointee (overload 3) of the result yields an undefined state.
 
-!!! danger "Undefined behavior for numeric conversions"
-
-    Conversions between numeric types are performed by the corresponding
-    `from_json()` implementation using the target C++ type. When converting
-    between numeric types, the library does not check whether the source
-    value is representable by the target type.
-    
-    If the source value is outside the range of the target type, the behavior
-    is the same as the corresponding C++ conversion. In particular, converting
-    a floating-point value to an integer type that cannot represent the value
-    results in undefined behavior.

-    Numeric conversions are performed according to the corresponding C++ conversion rules. The library does not perform
-    range checks when converting between numeric types.
-    
-    In particular, conversions from floating-point values to integer types, or conversions to integer types with a
-    smaller range than the stored value, may produce implementation-defined or undefined behavior if the source value
-    cannot be represented by the target type.
-    
-    Applications requiring checked conversions should inspect the stored number type with
-    [`is_number_float()`](../../api/basic_json/is_number_float.md),
-    [`is_number_integer()`](../../api/basic_json/is_number_integer.md),
-    [`is_number_unsigned()`](../../api/basic_json/is_number_unsigned.md), or
-    [`type()`](../../api/basic_json/type.md), and perform explicit range checks before converting to a narrower type.
-
 The rationale is twofold:
 
 1. JSON does not define a number type or precision (see above).
