func NotNaN() TestDeep
NotNaN
operator checks that data is a float and is not not-a-number.

func CmpNotNaN(t TestingT, got interface{}, args ...interface{}) bool
CmpNotNaN is a shortcut for:
Cmp(t, got, NotNaN(), args...)
See above for details.
Returns true if the test is OK, false if it fails.
args… are optional and allow to name the test. This name is
used in case of failure to qualify the test. If len(args) > 1
and
the first item of args is a string
and contains a ‘%’ rune
then
fmt.Fprintf
is used to compose the name, else args are passed to
fmt.Fprint
. Do not forget it is the name of the test, not the
reason of a potential failure.
