Returns 1 if number ≥ step; returns 0 (zero) otherwise. Use this function to filter a set of values. For example, by summing several GESTEP functions you calculate the count of values that exceed a threshold.
If this function is not available, and returns the #NAME? error, install and load the Analysis ToolPak addin.
How?
 On the Tools menu, click AddIns.
 In the AddIns available list, select the Analysis ToolPak box, and then click OK.
 If necessary, follow the instructions in the setup program.
Syntax
GESTEP(number,step)
Number is the value to test against step.
Step is the threshold value. If you omit a value for step, GESTEP uses zero.
Remark
If any argument is nonnumeric, GESTEP returns the #VALUE! error value.
