Hello CentOS List Members,
Thoughts as to why my BC functions aren't properly converting between bases?
Decimal to binary or hex works fine, but not binary or hex to decimal and so forth. No doubt the syntax is in some way wrong, but when I test from the CLI and the right values are returned, I have to wonder.
Other than a few other define statements, the only other option I have set is scale=5 in my bcrc.
In reference to the order of (o|i)base parameters, I have specified obase before ibase [0]. [0] http://docstore.mik.ua/orelly/unix/upt/ch49_03.htm
See below for my examples. Thanks!
]$ echo "bin_to_dec(1001)" | bc 1001 # should be decimal 9
]$ echo "obase=10; ibase=2; 1001" | bc 9
]$ grep bin_to_dec ~/.bcrc define bin_to_dec(b) { obase=10; ibase=2; return b; }

]$ echo "hex_to_dec(AB)" | bc 99 # should be decimal 171
]$ echo "obase=10; ibase=16; AB" | bc 171 ]$ echo "obase=A; ibase=16; AB" | bc 171
]$ grep hex_to_dec ~/.bcrc define hex_to_dec(h) { obase=A; ibase=16; return h; }
