  • dfmaf128
  • dfmal

• Canonical : [libc][math] Add iscanonical functions to math.yaml #199317

  • iscanonical
  • iscanonicalf

Adding iscanonical in #199317 . : )

Hi! I observed that there exists

- name: atan2f128
    standards:
      - stdc
    return_type: float128
    arguments:
      - type: float128
      - type: float128
    guard: LIBC_TYPES_HAS_FLOAT128

but no other transcendental function supports float128.

I'll go ahead and add the _Float128 variants of most/all functions mentioned in the first comment in this thread.

Hi, I’d like to work on the sinh, asinh, cosh, acosh, tanh, and atanh functions. Could you please assign this issue to me?

[Sukumarsawant]

@ArnavM21git you can work on Error, Gamma Functions and fma,

@skandanyal on issignalling family

and @iamaayushrivastava on trigonometric ones,
It would be better to review separately.

Adding Error, Gamma Functions and Fma in math.yaml in #199340 (comment)

Hello! Thank you for assigning the work. I'll take it up and execute it at my earliest convenience.

feel free to add a comment listing the functions here so can add into the tracking issue

Um... I'm sorry, I got confused and I happened to close that particular branch.
But here are the functions which were originally added -

• atanhf128
• acoshf128
• acosf128
• asinf128
• asinhf128
• cosf128
• coshf128
• cospif128
• sinf128
• sinhf128
• sinpif128
• tanf128
• tanhf128
• tanpif128

I can take up the job to add them to math.yaml, and even implement them further if required.

Hi, thank you for assigning the work. I've started working on the trigonometric functions.
