FTS1_RNAND

Replaces NaN values with bad values in a vector of 64-bit IEEE floating-point numbers

Description:

This routine replaces any IEEE not-a-number (NaN) values present in a vector of 64-bit IEEE-754 floating-point numbers to the standard _DOUBLE bad-pixel value. Also converted to the standard bad-pixel value are values who exponent is greater than maximum provided by the host machine.

Invocation

CALL FTS1_RNAND( EL, BUF, STATUS )

Arguments

EL = INTEGER (Given)
The number of IEEE numbers to be processed. An expression must not be given.
BUF( EL ) = DOUBLE PRECISION (Given and Returned)
The IEEE numbers to be cleansed of NaN values.
STATUS = INTEGER (Given and Returned)
The global status.
