it fixes the issue This is probably the fastest solution, but the where function does trigger the error as it precalculates the solutions: code :
import numpy as np
n = 4
xy = np.random.randint(4, size=(n,n)).astype(float)
x_norm = np.random.randint(4, size=(n,n)).astype(float)
y_norm = np.random.randint(4, size=(n,n)).astype(float)
xy_norm = x_norm*y_norm
edge_map = np.where(xy_norm == 0, xy_norm, xy/xy_norm)
print(xy)
print(xy_norm)
print(edge_map)

I wish this helpful for you I have a data.frame that looks like: code :
library(data.table)
data<fread("a b c d
1 2 NA 1
NA 2 2 1
3 2 NA 1
NA NA 20 2")
names_to_loop<names(data)
names_to_loop<names_to_loop[names_to_loop!="c"&names_to_loop!="d"]
for (ntl in names_to_loop){
set(data,j=ntl,value=ifelse(is.na(data[[ntl]]),data[["c"]]/data[["d"]],data[[ntl]]))
}
data[,c:=NULL]
data[,d:=NULL]
> data
a b
1: 1 2
2: 2 2
3: 3 2
4: 10 10

Javascript division error using division operator

I hope this helps . Floating point arithmetic in Javascript is broken and in general as well. It has nothing to do with division, it will return false if you don't do division since you are checking float value.
