Examples

import mir.test: shouldApprox;

geometricCDF(-1.0, 0.5).shouldApprox == 0; // UFCS chaining deduces this as size_t instead of a floating point type
0.geometricCDF(0.5).shouldApprox == 0.5;
1.geometricCDF(0.5).shouldApprox == 0.75;
2.geometricCDF(0.5).shouldApprox == 0.875;

geometricCDF(-1.0, 0.25).shouldApprox == 0; // UFCS chaining deduces this as size_t instead of a floating point type
0.geometricCDF(0.25).shouldApprox == 0.25;
1.geometricCDF(0.25).shouldApprox == 0.4375;
2.geometricCDF(0.25).shouldApprox == 0.578125;
2.5.geometricCDF(0.25).shouldApprox == 0.578125;
