Are you facing the call to undefined function bccomp() in Magento 2? Recently, I faced the same error while working on a client’s site.
Here, I am sharing the solution that worked for me.
Magento is an open-source e-commerce platform written in Php language. It requires a supported version of Php along with several libraries to function properly. One such required Php extension is the BCMath.
Magento uses various functions of BCMath Php extension at various steps.
For example, the bccomp() function compares the values of two long numbers during add-to-cart. In case the BCMath extension is missing, all those features may get affected.
In the present case, the customer was not able to add a product to the cart. On checking the error log of Magento 2 I found the following:
Call to undefined function MagentoInventorySalesModelIsProductSalableForRequestedQtyConditionbccomp()
Feel relaxed! I got a 100% working solution to this.
