isnan ( double )

intisnan(double)

tests whether d is NaN

Parameters
floating point value.
Return Value
non-zero if d is NaN. Otherwise, 0 is returned.

isinf ( double )

intisinf(double)

test for infinity or not-a-number

Parameters
floating point value to test.
Return Value
1 if the number d is Infinity, otherwise 0.

finite ( double )

intfinite(double)

Test for finity.

Parameters
floating point value to test.
Return Value
a nonzero value if the x parameter is a finite number; that is, if d is not +-, INF, NaNQ, or NaNS.
