A prvalue of a floating-point type can be converted to a prvalue of an
|
| 4 |
integer type. The conversion truncates; that is, the fractional part is
|
| 5 |
discarded. The behavior is undefined if the truncated value cannot be
|
| 6 |
+
represented in the destination type.

[*Note 1*: If the destination type is `bool`, see

A prvalue of an integer type or of an unscoped enumeration type can be
|
| 12 |
+
converted to a prvalue of a floating-point type. The result is exact if
|
| 13 |
possible. If the value being converted is in the range of values that
|
| 14 |
can be represented but the value cannot be represented exactly, it is an
|
| 15 |
*implementation-defined* choice of either the next lower or higher
|
| 16 |
+
representable value.
|
| 17 |
+
|
| 18 |
+
[*Note 2*: Loss of precision occurs if the integral value cannot be
|
| 19 |
+
represented exactly as a value of the floating type. — *end note*]
|

If the value being converted is outside the range of values that can be
|
| 22 |
represented, the behavior is undefined. If the source type is `bool`,
|
| 23 |
the value `false` is converted to zero and the value `true` is converted
|
| 24 |
to one.
