+The Hashicorp Configuration Language ( HCL ) does not support user defined functions. It only supports AND, OR and NOT logical operations. HCL is not meant for generic programming but I don't see an use case for a logarithm function in a language meant to provision infrastructure either. So......
+<lang terraform>
+variable "a" {
+  type    = bool
+  default = true
+}
+variable "b" {
+  type    = bool
+  default = false
+}
+output "a_and_b" {
+  value = var.a && var.b
+}
+output "a_or_b" {
+  value = var.a || var.b
+}
+output "not_a" {
+  value = !var.a
+}
+</lang>
+Invocation and output :
+<pre>
+$ terraform apply -var="a=true" -var="b=false" -auto-approve
+No changes. Your infrastructure matches the configuration.
+Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.
+Apply complete! Resources: 0 added, 0 changed, 0 destroyed.
+Outputs:
+a_and_b = false
+a_or_b = true
+not_a = false
