add:
"formData.b" (val) {
if (this.formData.a && this.formData.b) {
this.formData.c = parseFloat(this.formData.a) - parseFloat(this.formData.b);
}
},
"formData.c"(val) {
if (this.formData.a && this.formData.c) {
this.formData.b = parseFloat(this.formData.a) - parseFloat(this.formData.c);
}
}, when you enter a value of 0.4 for the sum of 6 ~ # b at run time, the value of b changes to 0.4000000000000000. as shown in the figure below, how to solve it?
