StepCk |
Function (ROM Call 0x1DD) |
Verifies that the input min, max, and step values are valid in parametric or polar mode.
StepCk verifies that the input min, max, and step values in the array pointed to by
indep are valid values for the independent variable in parametric mode
(tmin, tmax, and tstep) or polar mode (θmin, θmax, and θstep). The
function will return to the calling routine if the values are valid, otherwise an
error is thrown.
indep is a pointer to an array of floating-point values where
indep[0] = min, indep[1] = max, and indep[2] = step.
An error is thrown if the input values are not valid for the independent
variable in parametric mode or polar mode, such as the step value being
negative when it should have been positive for the given min and max.
