Discrete variable in optimization

Dear sirs, I have a variable x whose min. and max value are 0.900 and 1.00. I have randomly generated its value between its min and max limits. suppose the ans=0.984. I want that the ans should be discrete in the step of 0.025 ie. only five ans. are feasible. They are 0.900, 0.925, 0.950, 0.975 and 1.000. so i want to know matlab command/program/equation using which i can convert the ans(=0.984) into nearest discrete value(i.e.0.975). Thanks in advance

floor((x - 0.900)/0.025) * 0.025 + 0.900
