fcmp, a Python module extension to compare two floats:
To compare two floating precision numbers ("reals", 3.4, 5.89e+03, etc.) you need an epsilon or radious within which the numbers are judge equal. There is no alternative. In base 10, 1.0/3.0 is not 0.33333 nor 0.333333333333 etc. A nine digit precision (default) will call the former less than 1/3 and the latter equal to 1/3. However, the radious is only relative, floating, as the precision in these numbers.
Floats are basically written inside computers (and python) as m * (2 ** e) . A mantissa, m, and an exponent, e. The exponents are first compared and if equal, then the mantisas are compared up to the precision required.
Please download the module extension (is in fact a simple C wraper using swig, for a function taken from the gsl library) and follow the instructions within: fcmpClinical Trials
