Floating-point environment. Handling of floating-point rounding and exceptions (overflow, division by zero, etc.). The types, vars and procs are bindings for the C standard library <fenv.h> header.

template minimumPositiveValue(T: typedesc[float32]): float32
The smallest positive (nonzero) number that can be represented in a 32-bit floating-point type.
template epsilon(T: typedesc[float32]): float32
The difference between 1.0 and the smallest number greater than 1.0 that can be represented in a 32-bit floating-point type.
template minimumPositiveValue(T: typedesc[float64]): float64
The smallest positive (nonzero) number that can be represented in a 64-bit floating-point type.
template epsilon(T: typedesc[float64]): float64
The difference between 1.0 and the smallest number greater than 1.0 that can be represented in a 64-bit floating-point type.
