QFFE_213: "Invalid 'pow' arguments : '(value1, value2)'"

Impossible to raise the specified base to the specified power.

Cause

• The base is equal to 0 while the power is negative

  pow(1+t, t)

  Invalid 'pow' arguments : '(0, -1)' for t = -1

• The base becomes equal to 0 and the power becomes negative due to rounding errors

  pow(1 + 1e-20 - 1, -2)	Invalid 'pow' arguments : '(0, -2)'
  pow(t, 1 - 1e300 / 1e150 ^ 2)	Invalid 'pow' arguments : '(0, -2.22045e-016)' for t = 0

Resolution

• Check that the values of the arguments are always acceptable.
• If the cause is in rounding errors, try to change the order of operations to reduce their impact.
