Test the ".1" and "1." cases which are assumed to be problematic on
MacOS (or may not have been supported before a recent update). Add more
tests with leading signs as well as whitespace instead of a sign.
The previous implementation accepted either empty integer or empty
fractional parts of a floating point number, but also when both parts
were missing ("." input). Insist in at least one of the parts to be
present.
Programmatic output of floating point numbers might choose to print
spaces instead of an explicit '+' sign, to align the output with the
result of formatting negative numbers yet achieve a screen appearance
similar to what humans would have written. Skip leading whitespace
before insisting in seeing either signs or digits or decimals.
Accept numbers like "123." where the period (dot) is present yet the
fractional part is empty. Adding a period but no additional digits is a
popular method of turning an otherwise integer literal into a float.
Compilers and strtod() routines accept this notation, too, so we have to
expect seeing such input.
The previous implementation only echoed the p/q conversion results _if_
the return code signalled success but the result was unexpected. Although
the errno value for failed conversion attempts (non-zero return codes)
is not too helpful, seeing which text input failed the test is desirable.
The VCD specification requests that timestamps will strictly increase as
one advances through the file. Add another check where the previous
implementation resulted in a tight loop and made the application stall.
Do print an error message and abort file processing in that case.
This fixes bug #1250.
Adjust the calculation of the '^' marker's position in T: lines of the
-O ascii/bits/hex output modules such that it matches the sample data
lines' layout. Add comments which discuss the motivation of the marker
position's calculation, which differs among each of those modules.
Strictly speaking -O bits was already correct. But I chose to adjust and
comment the logic such that multiple output modules follow a common
pattern. If performance is an issue, the bits.c change might be worth
reverting.
This commit fixes bug #1238.
