module

numerics

Defines utilities to work with numeric types.

You can import these APIs from the utils package. For example:

from utils.numerics import FPUtils

Structs

• ​FPUtils: Collection of utility functions for working with FP values.
• ​FlushDenormals: Flushes and denormals are set to zero within the context and the state is restored to the prior value on exit.

Functions

• ​nan: Gets a NaN value for the given dtype.
• ​isnan: Checks if the value is Not a Number (NaN).
• ​inf: Gets a +inf value for the given dtype.
• ​neg_inf: Gets a -inf value for the given dtype.
• ​max_finite: Returns the maximum finite value of type.
• ​min_finite: Returns the minimum (lowest) finite value of type.
• ​max_or_inf: Returns the maximum (potentially infinite) value of type.
• ​min_or_neg_inf: Returns the minimum (potentially negative infinite) value of type.
• ​isinf: Checks if the value is infinite.
• ​isfinite: Checks if the value is not infinite.
• ​get_accum_type: Returns the recommended type for accumulation operations.
• ​nextafter: Computes next representable value of arg0 in the direction of arg1.
• ​ulp: Computes the ULP (units of last place) or (units of least precision) of the number.
