Damien George 2b000474d9 py/lexer: Properly classify floats that look like hex numbers.
Eg 0e0 almost looks like a hex number but in fact is a float.

Damien George 79474c6b16 py: Remove unnecessary extra handling of padding of nan/inf.
C's printf will pad nan/inf differently to CPython.  Our implementation
originally conformed to C, now it conforms to CPython's way.

Tests for this are also added in this patch.

stijn 861670ba2a py: Implement mp_format_float for doubles and use where appropriate
This allows using (almost) the same code for printing floats everywhere,
removes the dependency on sprintf and uses just snprintf and
applies an msvc-specific fix for snprintf in a single place so
nan/inf are now printed correctly.

Damien George 7d414a1b52 py: Parse big-int/float/imag constants directly in parser.
Previous to this patch, a big-int, float or imag constant was interned
(made into a qstr) and then parsed at runtime to create an object each
time it was needed.  This is wasteful in RAM and not efficient.  Now,
these constants are parsed straight away in the parser and turned into
objects.  This allows constants with large numbers of digits (so
addresses issue #1103) and takes us a step closer to #722.

Damien George 12c66be2b8 tests: Add some tests to improve coverage.
Used gcov to find some parts of vm.c, runtime.c, obj.c that were not
covered by any tests.  Still need to use gcov more thoroughly.

David Steinberg 0b3014ce3a py: Add support for floats in mp_binary_{get,set}_val()
- This then provides support for floats in the struct package
2015-01-27 22:49:01 +02:00
David Steinberg 4c1a7e0d6a tests: Update float2int tests for new range classifications
- Tests vary based on build configuration (32/64-bit and internal int type).
- Added tests for exceptions raised on overflow of int type.

Damien George 6d1f5070ce lib/libm: Add frexp and modf functions; use in stmhal; add tests.

Damien George ad2307c92c py: Temporary fix for conversion of float to int when fits in small int.
Addresses issue #1044 (see also #1040).  Could do with a better fix.

Paul Sokolovsky 2c75665445 objstr: Fix %d-formatting of floats. 2014-12-31 02:21:19 +02:00
Paul Sokolovsky 12033df511 py: Partially fix float to int conversion.
This fixes conversion when float type has more mantissa bits than small int,
and float value has small exponent. This is for example the case of 32-bit
platform using doubles, and converting value of time.time(). Conversion of
floats with larg exponnet is still not handled correctly.

Damien George f04329e93b lib/libm: Add acosh, asinh, atanh, tan; get working with stmhal.
acoshf, asinhf, atanhf were added from musl.  mathsincos.c was
split up into its original, separate files (from newlibe-nano-2).
tan was added.

All of the important missing float functions are now implemented,
and pyboard now passes tests/float/math_fun.py (finally!).
