oph_cast¶

Description¶

Behaviour

It converts the measure array value type from input to output type. Possible conversions are:

• (oph_byte, oph_short, oph_int, oph_long, oph_float, oph_double) <-> (oph_byte, oph_short, oph_int, oph_long, oph_float, oph_double);
• (oph_byte, oph_short, oph_int, oph_long, oph_float, oph_double) -> (oph_complex_int, oph_complex_long, oph_complex_float, oph_complex_double);
• (oph_complex_int, oph_complex_long, oph_complex_float, oph_complex_double) -> (oph_complex_int, oph_complex_long, oph_complex_float, oph_complex_double).

With conversion from real to complex numbers, it adds imaginary parts as 0 while, in case of complex numbers -> real numbers, it returns an error.

Parameters

• input measure type: Ophidia typing. Supported types are: ‘oph_double’ ‘oph_float’ ‘oph_int’ ‘oph_long’ ‘oph_short’ ‘oph_byte’ ‘oph_complex_double’ ‘oph_complex_float’ ‘oph_complex_int’ ‘oph_complex_long’.
• output measure type: Ophidia typing. Supported types are: ‘oph_double’ ‘oph_float’ ‘oph_int’ ‘oph_long’ ‘oph_short’ ‘oph_byte’ ‘oph_complex_double’ ‘oph_complex_float’ ‘oph_complex_int’ ‘oph_complex_long’.
• measure: input measure.
• missingvalue : value to be considered as missing value in input data; by default it is NAN (for “oph_doubl” and “oph_float”).
• output_missingvalue : value to be considered as missing value in output data; by default it is NAN (for “oph_double” and “oph_float”).

Return type

Binary-array.

Examples

Cast an array of measures from oph_double to oph_complex_int.

oph_cast('OPH_DOUBLE','OPH_COMPLEX_INT',measure)

Operation type
