domainof
domainof(curve,number)
The DOMAINOF function has the following arguments:
curveThe curve for which the value is to be calculated.
numberThe Y-value for which to fnd the first corresponding X-value.
This functions calculates the first value on the domain axis for the specified value from the range axis. The functions scans the curve from the lowest range value to the highest, and returns the first domain (X) value where the range (Y) value is equal to the specified number.
If the range value is not found in the curve, the function returns the maximum integer value (2**31)-1.
