InterpolatingFunction::dprec

Details

  • This message is generated when the grid spacing is zero to within the precision of the inputs.
  • This message is generated while computing a value for an InterpolatingFunction expression.
  • This error can occur if the grid spacing is smaller than the uncertainty in the arguments that are passed to the InterpolatingFunction expression.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[InterpolatingFunction::dprec].

Examples

Basic Examples  (1)

The uncertainty in the machine-number argument that is passed to the InterpolatingFunction expression is larger than the width of the interval in which that number falls:

The interpolation can be computed without difficulty if the argument is a high-precision number or if the argument is exact:
