KPG1_CSUBx

Subtracts a constant from each element of a vectorised array

The routine subtracts a constant from each element of a vectorised array to produce a new array. Bad value checking is performed if required.

CALL KPG1_CSUBx( BAD, EL, A, CONST, B, NERR, STATUS )

Whether to check for bad values in the input array.

Number of array elements to process.

Input array.

Constant to be subtracted from each array element.

Output array.

Number of numerical errors which occurred while processing the array.

The global status.

There is a routine for each numeric data type: replace " x" in the routine name by D, R, I, W, UW, B or UB as appropriate. The arrays supplied to the routine must have the data type specified.
This routine will handle numerical errors (i.e. overflow) by assigning the appropriate " bad" value to affected output array elements. If the constant supplied cannot be converted to the data type of the arrays without overflow, then all elements of the output array will be assigned this bad value and NERR will return the value of EL.
