.Sh DESCRIPTION
The
.Nm prop_number
family of functions operate on a numeric value property object type.
All values are unsigned and promoted to the type
.Sq uintmax_t .
.Bl -tag -width "xxxxx"
.It Fn prop_number_create_integer "uintmax_t val"
Create a numeric value object with the value
.Fa val .
.It Fn prop_number_copy "prop_number_t number"
Copy a numeric value object.
.It Fn prop_number_size "prop_number_t number"
Returns 8, 16, 32, or 64, representing the number of bits required to
hold the value of the object.
.It Fn prop_number_integer_value "prop_number_t number"
Returns the integer value of the numeric value object.
.It Fn prop_number_equals "prop_number_t num1" "prop_number_t num2"
Returns
.Dv TRUE
if the two numeric value objects are equivalent.
.It Fn prop_number_equals_integer "prop_number_t number" "uintmax_t val"
Returns
.Dv TRUE
if the object's value is equivalent to
.Fa val .
