Use the conditional operator in your c function - if val is Infinity (or -Infinity, I suppose), display NaN instead, otherwise display val:
function c(val) {
document.getElementById("d").value = (val === Infinity || val === -Infinity) ? 'NaN' : val;
}
function math(val) {
document.getElementById("d").value += val;
}
function e() {
try {
c(eval(document.getElementById("d").value))
} catch (e) {
c('Error')
}
}<br><br>

you can add a check in your functin c() like this
function c(val)
{
if ( val == Infinity || val == -Infinity )
val = NaN;
document.getElementById("d").value=val;
}
