Converting pow() to integer

[cheyner11]

I have a math issue. I am building a mortgage calculator and I cannot seem to get it to work because the pow() function makes the number an exponent - 6.37 E 45

How do I convert this to a full integer.

Thanks,

Jeremy

I think your calculator may be buggy if you are getting numbers that large (or that small, if that's a "-" in front of it).  PHP's integers cannot hold numbers of that size.

The calculator is only doing: 1.5 ^ 360

And it is coming back with that exponent number. I just need a way to convert it to a real number.

Yes, still too large...

Too clarifiy it for you:

hth.

Only??? You are multiplying 1.5 by itself 360 times. That is a large number.

What are you trying to calculate?

That would match a principal with an interest rate of 50% PER MONTH over a period of 30 years.

If you wanted an interest rate of 10% PER YEAR over 30 years, you would want (1.1)^30, which is around 17.45, much more reasonable.
