Enter input data not exceeding #0900
in BCD form.
Result data has four significant
digits, fifth
and higher digits are ignored.
The result for cos(0) will be
0.9999, not 1.
APR(142) linear extrapolation is specified when C is a word address.
The content of word C specifies the number of coordinates in a data table start-
ing at C+2, the form of the source data, and whether data is BCD or binary.
Bits 00 to 07 contain the number (binary) of line coordinates less 1, m–1. Bits 08
to 12 are not used. Bit 13 specifies either f(x)=f(S) or f(x)=f(X
m
–S): OFF specifies
f(x)=f(S) and ON specifies f(x)=f(X
m
–S). Bit 14 determines whether the output is
BCD or binary: OFF specifies BCD and ON specifies binary. Bit 15 determines
whether the input is BCD or binary: OFF specifies BCD and ON specifies binary.

The following example demonstrates the construction of a linear extrapolation
with 12 coordinates. The block of data is continuous, as it must be, from D00000
to D00026 (C to C + (2
(×
12 + 2)). The input data is taken from CIO 0010, and the
result is output to CIO 0011.
