step - generate a step function by comparing two values

genType step(genType edge, genType x);

genType step(float edge, genType x);

genDType step(genDType edge, genDType x);

genDType step(double edge, genDType x);

edge

Specifies the location of the edge of the step function.

x

Specify the value to be used to generate the step function.
