<td class="t-dcl-nopad"> </td> <td > (since C99) </td> </tr> Template:ddcl list end

Determines if the given floating point number arg has finite value i.e. it is normal, subnormal or zero, but not infinite or NAN. The macro returns an integral value.

Parameters

arg - floating point value

Return value

Nonzero integral value if arg has finite value, 0 otherwise.
