## Detailed Description

template<typename float_t>
class uhd::math::fp_compare::fp_compare_epsilon< float_t >

Class for floating-point comparisons using an epsilon.

At construction, you can specify the epsilon to use for the comparisons. This class, combined with the operators under it, allow for epsilon-comparisons of floats. An example is:

// Compare floats 'x' and 'y'. bool x_equals_y = (fp_compare_epsilon<float>(x) == y);

// Compare doubles 'x' and 'y'. bool x_equals_y = (fp_compare_epsilon<double>(x) == y);
