Syntax: ERF(L[, U])
L = Lower bound for integrating ERF, L=0
U = (Optional) Upper bound for integrating ERF
ERF returns the error function integrated between L and
U. The function is given by:
If U is omitted, ERF integrates between 0 and L:
Examples:
ERF(1) = 0.8427
ERF(0.35) = 0.3794
ERF(0.35, 0.89) = 0.4125
